YDNR (you did not read :P) I say he put a license and this implies he claimed copyright.

That's the thing. You don't 'claim' copyright. It is a right established by the Berne Convention. You would file a claim if your copyright were violated, but other than that, you control distribution of your original work as long as Sonny Bono says. :-)

Points for coining a new abbrev. YDNR is going into my "snarky, not explained" responses in emails. :-) "What does that mean?" "Oh, I often hit some keys for a macro on my home computer that don't expand on this machine."

Look at my original comment that started this subthread. If it's a derivative work (which it seems to be) Google owns the copyright to OP's image.
