I set that up a while ago but never finished.  That's one of the strange
things about how images are currently being handled - the images are set
to a relative path which doesn't really work too well for having
multiple aliases.

I wouldn't mind adding a link to the logos under "OSGeo Foundation".
We'll need a copy of the final logo usage guidelines uploaded as well,
so we can link to them from that page.
