MultimediaViewer is a MediaWiki extension that gives the user of a wiki a slightly nicer interface for viewing full-size, or nearly full-size, images in their browser without extraneous page loads or confusing interstitial pages. It is currently a beta feature deployed in all Wikimedia sites.

Currently it has this little problem:

In the MediaViewer it's made really easy to re-use files from the wiki either
on-wiki or using a deep link. It is however not clear what the license is for
the file that someone can re-use. To get to know this, a user needs to click
some more and look it up by clicking "License information" or on "Learn more on
Wikimedia Commons" (which is blocked by the pop-up with the links).
