Other languages:

This extension comes with MediaWiki 1.31 and above. Thus you do not have to download it again. However, you still need to follow the other instructions provided.

Die Erweiterung MultimediaViewer' gibt dem Benutzer eines Wikis eine andere visuelle Oberfläche, um Bilder in voller oder fast voller Größe in seinem Browser anzuzeigen, ohne dass es zu unerwünschten Seitenaufrufen oder unterbrechenden Seiten kommt.

Installation

Option A: use Vagrant. See the MediaWiki-Vagrant page for instructions to get a MediaWiki installation going with a Vagrant virtual machine system.

Then do vagrant enable-role multimediaviewer and then vagrant provision.

Option B: Manuell installieren.

First, consider installing Extension:BetaFeatures . It may be helpful to hide the media viewer feature behind a preference. If you don't install this, it will be enabled everywhere. MultimediaViewer uses the GetBetaFeaturePreferences hook, which is created and run from BetaFeatures, to register this preference.

You'll also likely want to download Extension:CommonsMetadata - it's not a hard requirement, but without it you won't get very much information in your lightboxes.

Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens MultimediaViewer im Ordner extensions/ ablegen.
Folgenden Code am Ende Ihrer LocalSettings.php hinzufügen:
```
wfLoadExtension( 'MultimediaViewer' );
```
Done – Zu Special:Version in dem Wiki (bei Einstellung auf deutsch nach Spezial:Version) navigieren, um die erfolgreiche Installierung der Erweiterung zu überprüfen.

Konfiguration

$wgMediaViewerIsInBeta will register a preference with BetaFeatures if set to "true"

$wgMediaViewerEnableByDefault and $wgMediaViewerEnableByDefaultForAnonymous will determine whether MMV is enabled by default for everyone and for anonymous users, respectively.

They both default to true. $wgDefaultUserOptions[ 'multimediaviewer-enable' ] = 1; can be used as a replacement for $wgMediaViewerEnableByDefault.

$wgMediaViewerUseThumbnailGuessing will improve performance when enabled, but can be fragile depending on how the wiki is set up (it will probably work fine if you use a 404 handler).

Forced download

To ensure files are offered for download and not viewed in the user's browser following a click on the Download … button, the server has to be configured, except when using vagrant:

If the requested URL to an image directory contains the download query parameter, the Content-Disposition-header must be set to attachment. This can be achieved in Apache and compatible servers using mod_rewrite and mod_headers in a .htaccess file. Varnish configuration can look like this.

Verwenden der Erweiterung

First thing, before testing, is to make sure you're logged in and you have the preference enabled: Log in to the wiki and go to Special:Preferences, then visit the "Beta features" tab and check the appropriate box.

Next, go to a page that has a thumbnail on it. Try clicking on the image or on the "expand" icon near it. The lightbox should pop up and give you a bigger view of the image.

If you'd prefer, there's an exported test environment that you can use via Special:Import to quickly set up a suitable testing environment.

Vorlagen

Multimedia Viewer and Upload Wizard needs several templates to show data of photos. Speichern Sie diesen Code als XML-Datei und importieren Sie ihn in Ihr Wiki.
