The MultimediaViewer extension gives the user of a wiki a different interface for viewing full-size, or nearly full-size, images in their browser without extraneous page loads or confusing interstitial pages.
First, consider installing Extension:BetaFeatures. It may be helpful to hide the media viewer feature behind a preference. If you do not install this, it will be enabled everywhere.
You will also likely want to download Extension:CommonsMetadata. It is not a hard requirement, but without it you will not get very much information into the boxes showing details about the images.

Developers and code contributors should install the extension from Git instead, using:
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.
- If using Vagrant, install with
vagrant roles enable multimediaviewer --provision
$wgMediaViewerIsInBetawill register a preference with BetaFeatures if set to "true"
$wgMediaViewerEnableByDefaultForAnonymouswill determine whether MMV is enabled by default for everyone and for anonymous users, respectively.
They both default to
$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
This can be achieved in Apache and compatible servers using mod_rewrite and mod_headers in a
Varnish configuration can look like this.
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.
|This extension is being used on one or more Wikimedia projects. This probably means that the extension is stable and works well enough to be used by such high-traffic websites. Look for this extension's name in Wikimedia's CommonSettings.php and InitialiseSettings.php configuration files to see where it's installed. A full list of the extensions installed on a particular wiki can be seen on the wiki's Special:Version page.
