Extension:MultimediaViewer/hi

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
First, consider installing. 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. 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
They both default to. can be used as a replacement for.
 * 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.
 * 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 using mod_rewrite and mod_headers in a  file. Varnish configuration can look like this.

Usage testing
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
MultimediaViewer and need several templates to show data of photos. Just save this code in a xml file and import it in your wiki.
