Yes and no. Attach:Groupname/an-image.png (without a dot!) correctly 
references an image in a different group's uploads directory. But I 
don't see an easy way to tell pmwiki to retrieve the "graphic" PTV as 
Attach:GroupA/an-image.png instead of just Attach:an-image.png, if 
that's what the author entered -- I can't rely on people remembering to 
insert a groupname when they set up a (:graphic: Attach:an-image.png :) PTV.

And I do not understand the difference between 
Attach:Groupname./file.ext and Attach:Groupname/file.ext, since the 
latter seems to work.
