Tato stránka vysvětluje syntaxi obrázku při editaci wiki. Aby bylo možné použít na stránce obrázek, tak ho musíte nejprve vy, nebo někdo jiný do wiki vložit.

Link na obrázek, který je uložen na MediaWiki serveru tvoří, kromě jména souboru, také prefix jmenného prostoru File: (i když stále lze použít i původní jmenný prostor Image:). Jmenný prostor Media: lze také použít, pokud chceme vytvořit přímý link na vložený soubor (obrázek pak nebude interpretován jako stránka MediaWiki).

Podporované formáty obrázkůEdit

Ve výchozím stavu jsou podporovány následující formáty:

  • .jpg nebo .jpeg : bitmapový obrázek je komprimovaný podle standardu JPEG (ztrátový formát, který se hodí především pro fotografie).
  • .png : bitmapový obrázek ve formátu PNG (formát Portable Network Graphic specifikovalo konsorcium W3).
  • .gif : bitmapový obrázek ve formátu GIF (Graphics Interchange Format).

Další formáty, které používá Wikimedia, a s nimiž se lze setkat i jinde (jejich použití, ale může vyžadovat další nastavení, takže ve výchozím nastavení nemusí být dostupné):

  • .svg : vektorové obrázky ve formátu SVG (formát Scalable Vector Graphics specifikovalo konsorcium W3). Viz Manual:Image Administration#SVG.
  • .tiff : Tag Image format file - neoficiální standard pro ukládání obrázku ve formátu pro tisk. Často se používá u fotografií určených pro archivaci, které mají mít zachováno vysoké rozlišení. Obvykle se používá s Extension:PagedTiffHandler.
  • .ogg, .oga, .ogv : Formát ogg je určen pro multimediálné soubory (může obsahovat obraz i zvuk). Nejde sice přímo o obrazový formát, ale chová se podobně. Obvykle se používá s Extension:OggHandler.
  • .pdf : vícestránkové dokumenty ve formátu PDF (Specifikace pro Portable Document Format pochází od Adobe). Obvykle se používá v kombinaci s Extension:PdfHandler
  • .djvu : bitmapový formát s wavelet kompresí pro vícestránkové dokumenty DejaVu (nejčastěji se s ním lze setkat u naskenovaných knih). Viz Manual:How to use DjVu with MediaWiki
    Ze souboru ve formátu .pdf or .djvu lze v jednom okamžiku na stránce zobrazit pouze jednu stránku.

Podporované jsou i další typy souborů, ale ty nelze zobrazit jako obrázek.

Vložení obrázkuEdit

SyntaxeEdit

Plná syntaxe pro zobrazení obrázku vypadá takto:

[[File:filename.extension|options|caption]]

Parametr options zastupuje řadu dalších parametrů, které jsou od sebe, odděleny rourou (|), které však nemusí být uvedeny vůbec:

  • Parametr určující formát zobrazení: lze použít vždy pouze jeden z následujících border, frameless, frame, thumb (nebo thumbnail);
    rozhoduje o tom, jak bude vložený obrázek na stránce vypadat a kam bude vůči zbytku stránky umístěn.
  • Parametr, kterým lze upravit velikost: opět lze použít jen jedna z následujících možností
    • {šířka}px — Upraví velikost obrázku tak, aby jeho šířka odpovídala uvedené šířce v pixlech, bez ohledu na výšku;
    • x{výška}px — Upraví velikost obrázku tak, aby jeho výška odpovídala uvedené výšce v pixlech, bez ohledu na šířku;
    • {šířka}x{výška}px — Upraví velikost obrázku tak, aby se všemi rozměry nešel do uvedené šířky a výšky v pixlech;
    • upright — Upraví velikost obrázku tak, aby výsledná velikost vyhovovala preferencím uživatele (hodí se především u obrázků, které jsou vyšší než širší).
    Povšimněte si, že u obrázku bude vždy zachován poměr stran a rozměry lze upravit pouze tak, že dojde k jeho zmenšení.
    Maximální velikost zobrazeného obrázku závisí na použitém formátu a velikosti výchozího souboru (což může být závislé na jeho typu).
  • Parametr určující horizontální zarovnání: může být uveden pouze jeden z následujících left, right, center, none;
    Ovlivňuje horizontální zarovnání obrázku vůči textu (ať již je vložen jako řádkový, plovoucí či blokový element). Ve výchozím hodnota zarovnání není žádná.
  • Parametr pro vertikální zarovnání: může být baseline, sub, super, top, text-top, middle, bottom, text-bottom;
    Ovlivňuje vertikální zarovnání obrázku vůči textu, který se nachází spolu s ním v rámci stejného blokového elementu před ním, nebo za ním (výchozí hodnota vertikálního zarovnání je middle). Parametr nemá vliv, pokud je obrázek vložen jako plovoucí element.
  • Parametr odkaz: může být buď
    • link={cíl odkazu} — Umožňuje změnit cíl vygenerovaného odkazu (zpravidla na nějakou jinou stránku, nebo URL), který je aktivní nad celou plochou vygenerovaného obrázku; např. [[File:Example.jpg|20px|link=http://www.wikipedia.org]] se vygeneruje jako Example.jpg (externí link), zatím co [[File:Example.jpg|20px|link=MediaWiki]] jako Example.jpg (interní link).
    • link= (bez uvedené hodnoty) — (MediaWiki 1.14+) Se vygeneruje jako obrázek bez aktivního linku; [[File:Example.jpg|20px|link=]] se vygeneruje jako Example.jpg.
      • ! Pokud nastavíte |link=| (bez nějaké hodnoty), pak se nevygeneruje žádný title. (Viz bugzilla:21454.)
  • Další možné parametry:
    • alt={alternative text} — (MediaWiki 1.14+) Defines the alternative text (maps to the HTML attribute alt="..." of the generated <img /> element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).
    • page={number} — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file).
    • class={html class} — (MediaWiki 1.20+) Defines classes (maps to the HTML attribute class="..." of the generated <img /> element).
    • lang={language code} — (MediaWiki 1.22+) For SVG files containing <switch> statements varying on a systemLanguage attribute, selects what language to render the file in. The default is always English, even on non-English wikis.

If a parameter does not match any of the other possibilities, it is assumed to be the caption text. Caption text shows below the image in thumb and frame formats, or as tooltip text in any other format. Caption text displayed in the thumb and frame formats may contain wiki links and other formatting. MediaWiki extensions can add additional options.

If 'alt' is not specified and a caption is provided, the alternative text will be created automatically from the caption, stripped of formatting.

FormatEdit

The following table shows the effect of all available formats.

When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option upright=N, where N is the image's aspect ratio (its width divided by its height, defaulting to 0.75). The alternative is to specify the desired maximum height (in pixels) explicitly.

Note that by writing thumb={filename}, you can use a different image for the thumbnail.

Size and frameEdit

Among different formats, the effect of the size parameter may be different, as shown below.

  • For how it appears when its size is not specified, see Format section above.
  • When the format is not specified, or only bordered, the size can be both reduced and enlarged to any specified size.
  • In the examples below, the original size of the image is 400 × 267 pixels.
  • An image with frame always ignores the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.
  • The size of an image with thumb can be reduced, but can not be enlarged beyond the original size of the image.

Vertical alignmentEdit

The vertical alignment options take effect only if the image is rendered as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.

To show the alignment result more clearly, the text spans are overlined and underlined, the font-size is increased to 200%, and the paragraph block is outlined with a thin border; additionally images of different sizes are aligned:

text top: Example.jpg Example.jpg Example.jpg text

text text-top: Example.jpg Example.jpg Example.jpg text

text super: Example.jpg Example.jpg Example.jpg text

text baseline: Example.jpg Example.jpg Example.jpg text

text sub: Example.jpg Example.jpg Example.jpg text

text default: Example.jpg Example.jpg Example.jpg text

text middle: Example.jpg Example.jpg Example.jpg text

text text-bottom: Example.jpg Example.jpg Example.jpg text

text bottom: Example.jpg Example.jpg Example.jpg text

Notes:

  1. The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
    • the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
    • the additional line spacing which may be added by superscripts and subscripts.
  2. However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
  3. The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
  4. The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span). When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.
  5. The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and may depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

Stopping the text flowEdit

On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing <br clear=all> (or if you prefer, <div style="clear: both"></div>) before the text that should start below the floating image. (This may also be done without an empty line by wrapping the section with the floating images with <div style="overflow: hidden">…</div>, which clears all floats inside the div element.)

All images rendered as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for centered images).

Altering the default link targetEdit

The following table shows how to alter the link target (whose default is the image description page) or how to remove it. Changing the link does not alter the format described in the previous sections.

Warning:

The licencing requirements on your wiki may not allow you to remove all links to the description page that displays the required authors attributions, the copyrights statements, the applicable licencing terms, or a more complete description of the rendered image (including its history of modifications).
If you change or remove the target link of an image, you will then have to provide somewhere else on your page an explicit link to this description page, or to display the copyright and author statement and a link to the applicable licence, if they are different from the elements applicable to the embedding page itself.
Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.

Rendering a gallery of imagesEdit

Gallery syntaxEdit

It's easy to make a gallery of thumbnails with the <gallery> tag. The syntax is:

<gallery>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>

Note that the image code is not enclosed in brackets when enclosed in gallery tags.

Captions are optional, and may contain wiki links or other formatting. Some of the parameters controlling thumb output can also be used here, specifically the ones that modify the file (as opposed to ones that control where in the page the image falls). For example, with multi-paged media like pdfs, you can use code like page=4.

The File: prefix can be omitted.

For example:

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg| ''italic caption''
File:Example.jpg|on page "{{PAGENAME}}"
</gallery>

is formatted as:

Mode parameterEdit

MediaWiki version: 1.22

Starting in 1.22 we have an experimental mode parameter, taking options as follows:

  • traditional is the original gallery type used by MediaWiki.
  • nolines is similar to traditional, but with no border lines.
  • packed causes images to have the same height but different widths, with little space between the images. The rows in this responsive mode organize themselves according to the width of the screen.
  • packed-overlay shows the caption overlaid on the image, in a semi-transparent white box.
  • packed-hover is similar to packed-overlay, but with the caption and box only showing up on hover.

For example:

<gallery mode="packed-hover">
Image:Astronotus_ocellatus.jpg|''[[commons:Astronotus ocellatus|Astronotus ocellatus]]'' (Oscar)
Image:Salmonlarvakils.jpg|''[[commons:Salmo salar|Salmo salar]]'' (Salmon Larva)
Image:Georgia Aquarium - Giant Grouper.jpg|''[[commons:Epinephelus lanceolatus|Epinephelus lanceolatus]]'' (Giant grouper)
Image:Pterois volitans Manado-e.jpg|''[[commons:Pterois volitans|Pterois volitans]]'' (Red Lionfish)
Image:Macropodus opercularis - front (aka).jpg|''[[commons:Macropodus opercularis|Macropodus opercularis]]'' (Paradise fish)
Image:Canthigaster valentini 1.jpg|''[[commons:Canthigaster valentini|Canthigaster valentini]]'' (Valentinni's sharpnose puffer)
Image:Flughahn.jpg|[[Image:POTY ribbon 2007.svg|25px]] ''[[commons:Dactylopterus volitans|Dactylopterus volitans]]'' (Flying gurnard)
Image:Fishmarket 01.jpg|''[[commons:Semicossyphus pulcher|Semicossyphus pulcher]]'' (California Sheephead)
Image:Pseudorasbora parva(edited version).jpg|''[[commons:Category:Pseudorasbora parva|Pseudorasbora parva]]'' (Topmouth gudgeon)
Image:MC Rotfeuerfisch.jpg|''[[commons:Category:Pterois antennata|Pterois antennata]]'' (Antennata Lionfish)
Image:Cleaning station konan.jpg|''[[commons:Novaculichthys taeniourus|Novaculichthys taeniourus]]''
Image:Synchiropus splendidus 2 Luc Viatour.jpg|''[[commons:Synchiropus splendidus|Synchiropus splendidus]]'' (Mandarin fish)
File:Psetta maxima Luc Viatour.jpg|''[[commons:Psetta maxima|Psetta maxima]]'' (Turbot)
File:Australian blenny.jpg|''[[commons:Category:Ecsenius|Ecsenius axelrodi]]''
</gallery>

Gives (mode: packed-hover):

Examples of the other modes:

mode="traditional"

mode="nolines"

mode="packed"

mode="packed-overlay"

Optional gallery attributesEdit

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:

<gallery {parameters}>
{images}
</gallery>
  • caption="{caption}": (caption text between double quotes for more than a word) sets a caption centered atop the gallery.
  • widths={width}px: sets the widths of the images, default 120px. Note the plural, widths.
  • heights={heights}px: sets the (max) heights of the images.
  • perrow={integer}: sets the number of images per row. 0 means automatically adjust based on width of screen.
  • showfilename={anything}: Show the filenames of the images in the individual captions for each image (1.17+).
  • mode={traditional|nolines|packed|packed-hover|packed-overlay}: See section above (1.22+).
The widths and heights parameters are taken more as suggestions than strict values for packed (and related) modes. Packed modes will adjust the width of images in order to make each row the same length.

Example:

Coding:

<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
</gallery>

Result:

Row of images that will wrap to browser widthEdit

The only thing that works for a row of images with varying widths is not to use "thumb" or "left" or "none". If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width. If necessary, narrow the browser window to see the images wrap to the next row.

[[File:Example.jpg|220px]]
[[File:Example.jpg|100px]]
[[File:Example.jpg|150px]]
[[File:Example.jpg|250px]]
[[File:Example.jpg|200px]]
[[File:Example.jpg|50px]]
[[File:Example.jpg|220px]]
[[File:Example.jpg|175px]]

Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg

Some wiki farms do not have all gallery options (such as "widths"). Also, sometimes one wants varying widths for images in a row. Outside of a gallery it is impossible to have individual captions for images in a row of images that will wrap to the browser width. Try it and see. Nothing works. Images will either overlap stuff on the right, or force a horizontal scroll bar.

Using a left float ("left") for some images, combined with "none" for some of the images, will not work consistently either, especially if there is also a right sidebar of images. Weird things will occur. At narrower browser or screen widths an image out of the row may appear far down the page after the end of the right sidebar of images.

Link behaviorEdit

By default an image links to its file description page. The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior.

Alternatively, you can create a text link to a file description page or to the file itself. See Help:Linking to files.

Display image, link it to another page or websiteEdit

Use "link=" option to link image to another page or website:

Clicking on the below image will take you to MediaWiki:

[[File:Wiki.png|50px|link=MediaWiki]]

Wiki.png

Clicking on the below image will take you to example.com:

[[File:Wiki.png|50px|link=http://example.com]]

Wiki.png

Display image, turn off linkEdit

Use "link=" option with no value assigned to turn link off entirely; the below image is not a link:

[[File:Wiki.png|50px|link=]]

Wiki.png


RequisitesEdit

Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Files at other websitesEdit

You can link to an external file available online using the same syntax used for linking to an external web page. With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.

[http://url.for/some/image.png]

Or with a different displayed text:

[http://url.for/some/image.png link text here]

Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):

[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]

which renders as: Example rich link text here.

If it is enabled on your wiki (see Manual:$wgAllowExternalImages), you can also embed external images. To do that, simply insert the image's url:

http://url.for/some/image.png

Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.

If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.
