[Mediawiki-l] Image's Accompanying Files

[Frederich, Eric P2173]

Is there a way to have a file, like a .xcf (Gimp file), or a .svg, or a
.vsd (Visio file) along with an image.

I have been uploading pictures of flow charts and such to our wiki.  It
would be nice if someone could have the Visio file to edit and then
upload a new version of both the Visio file and the corresponding image.

Anyone do this before?

Thanks,
~Eric
