Inter-wiki image display
WikiImages.org/Archive has the original problem statement.
There is a problem about superfluous use of disk space, caused by duplicated images: images across language pages, and various other sub-projects of wikimedia.
In addition to this disk space problem, there is an administration burden, of having to deal with many copies of the images. (copyright, etc)
WikiImages.org/Archive is one possible solution to this problem, and another, possibly simpler way of dealing with this problem is to enable a syntax to grab an image from another wikimedia server.
this requires a change in MediaWiki code.
Problems with this solutionEdit
A consumer might have to deal with 5 different servers, instead of just one, or two with the WikiImages.org solution.
