Not sure I've heard of that one. But it is entirely possible that some images may have come from there. I've been collecting various images for a long time. Sometimes I'll be looking through some old files of this or that and something will jump out at me. And sometimes, when i just can't think of what I want, i will do a google image search and see what pops up, but as far as using someone else's theme as a base for my own, I'm afraid you got that part wrong.
