"I'm watermarking all of my newer images with a signature and date now... lol!" I usually put the URL to my website in the corner, it's not so much a signature-thing, but rather a way for anyone who might have downloaded it to see where it came from, a ploy to get more visitors, maybe. :)
I've also wondered about Apophysis, I mean compared to other fractal generators it seems it cannot produce as many unique fractals, and there certainly are alot of them. It's only a matter of time before two people accidentally (or subconsciously (not simultaneously)) make two images similar enough to be mistaken as the same.
