A direct view URL which uses the 'Media:' special namespace currently brings up the Image:/File: page transparently, however it doesn't redirect you to the canonical URL, the way that using a non-canonical form of the Image/File namespace does.
To ensure links are pointed sensibly, an HTTP redirect should be issued here.
eg:
http://en.wikipedia.org/wiki/Media:Northern_Spotted_Owl.USFWS-thumb.jpg
->
http://en.wikipedia.org/wiki/File:Northern_Spotted_Owl.USFWS-thumb.jpg
Version: unspecified
