I've seen this in a few different places already, so I know it can be done, but not only am I confused as to HOW to do it, but I can't even think of what to call it to search for it :/ Basic idea - PHP places one image (defined by the user using a dropbox) in a 'field'. Based on more input by the user, it will place another image over it, creating a third image. It can layer endless amounts of images. For example: Let's say this is one image: (x's are black pixels and -'s are white ones) x---x-xx --x-xx-x -x-x-x-x And that this is another one: -xxx-x-- xx-x--x- x-x-x-x- And when you 'overlay' them you get: xxxxxxxx xxxxxxxx xxxxxxxx Or -------- -------- -------- Depending on what you specify. If you want working examples, ask me, I can get you some. If you know what I mean, though, please help! Thanks, Ghost //
