That's for text.
see above? It's not possible for images? There would be no technical reason why this shouldn't work.
See what Brion told you: "For a single integrated shared image repository, see $wgUseSharedUploads & co"
It's a different parameter. You make one wiki the place whose uploasd can be used by all your wikis . Then you make sure your transwikied pages only use images from that place (which can be the original wiki ;) ).
