SifJar said:hmmm, maybe some one could take two pictures (or more, doesn't matter), one of say a black page of paper, another of a white page, so they'd be completely different images, then open them in a hex editor and see what bits are the SAME. Then take that bit and put it in another image and see if that works. but if what the guy above ^^ suggests is true, that won't work either. but worth a try I think
I've tried it, doesn't work, though it's possible that I might have just done it wrong
