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 MultimediaViewer folder to your extensions/ 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
  • Yes 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

  • $wgMediaViewerEnableByDefault and $wgMediaViewerEnableByDefaultForAnonymous will determine whether MultimediaViewer is enabled by default for everyone and anonymous users, respectively. They both default to true.
  • $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.

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.
