The MultimediaViewer extension gives wiki users a different interface for viewing full-size or nearly full-size images in their browser without extraneous page loads or confusing interstitial pages.
Installation
You will also likely want to download Extension:CommonsMetadata. It is not a hard requirement, but without it, you will not get much information in the boxes showing details about the images.
On third-party wikis, even if you only use locally uploaded images, you need CommonsMetatada to populate the information in the boxes via a template holding information about the files.)
- Download and move the extracted
MultimediaViewerfolder to yourextensions/directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/MultimediaViewer - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'MultimediaViewer' );
- Configure as required
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Vagrant installation:
- If using Vagrant, install with
vagrant roles enable multimediaviewer --provision
Configuration
$wgMediaViewerEnableByDefaultand$wgMediaViewerEnableByDefaultForAnonymouswill determine whether MultimediaViewer is enabled by default for everyone and anonymous users, respectively. They both default totrue.$wgMediaViewerUseThumbnailGuessingwill 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.
Usage testing
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 set up a suitable testing environment quickly.
Templates
MultimediaViewer and UploadWizard need several templates to show data of photos. Save this code in an XML file and import it in your wiki.
