Extension:MultimediaViewer

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.

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

Then do  and then.

Option B: install manually.

First, consider installing. 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 hook, which is created and run from BetaFeatures, to register this preference.

You will also likely want to download - it is not a hard requirement, but without it you will not get very much information into the boxes showing details about the images.

Configuration

 * will register a preference with BetaFeatures if set to "true"


 * and will determine whether MMV is enabled  by default for everyone and for anonymous users, respectively.  They both default to  .    can be used as a replacement for.


 * 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  query parameter, the  -header must be set to. This can be achieved in Apache and compatible servers [https://gerrit.wikimedia.org/r/c/mediawiki/vagrant/+/120614/3/puppet/templates/content_disposition_attachment.conf.erb using mod_rewrite and mod_headers in a  file]. Varnish configuration can look [https://gerrit.wikimedia.org/r/c/operations/puppet/+/120617/7/templates/varnish/upload-frontend.inc.vcl.erb like this].

Using the extension
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.

Templates
Multimedia Viewer and Upload Wizard needs several templates to show data of photos. Just save this code in a xml file and import it in your wiki.
