Comment by gyaban: Since it is not a downloaded clipart, but something I created by myself specially for that entry, I think it is legal. At least, this is my understanding of the rules, and a shared opinion in several threads in the forums.
Comment by bspurgeon: * The flame: I created the fire texture using the "difference clouds" tool, then it was a *lot* of various painting, masking, wave and gradient effects.
Is that legal, or did it start as a photogragh? Looks like the cover of a book!
