Ah, sorry, I misunderstood. I assume you meant you remember you got it from DevArt but now can't find it again there?

You could create an icon and put something like "Yours? Tell me, I'll credit you" in the text.

And nope, it's not up for grabs when you can find it on teh googlemonster. I mean, you can find almost everything there, including all the copyrighted stuff.
