Ah, I see what happened. For the English wiki conversion, I changed all the external links to local images into [[image:...]] references. The external references to wikipedia images on the German site really are external, though, and they probably shouldn't have been translated. On the other hand, those images really should be moved to the new site so that the wikis are more independent, so I'm inclined to think that leaving them "broken" is the right thing to do, to encourage authors toput them into the new site. I'm open to other idea though.
