Nope. On the other hand, I would think that most of the effects that can be done in Apophysis can also be done in Photoshop using filters (I would guess under "Distort"), hence , no need. Try a few out. :-)
I lied. Between the "Nope." and the "On the other hand,", I should have mentioned that you can input an image if you so desire, but all that it does is salvage the colors from it, and that isn't always precisly accurate to what the eye would request. Try it out!
that is a very interesting question, and actually here's the science behind it:
The whole idea of fractal formulas being portable is the fact that you could take a HUGE poster sized image that would be several MB large, and reduce it to a couple KB in size as a formula. We can do this already, but you have to remember that Apophysis "plots" points based on a formula it's given. It's almost impossible to turn any random image into a formula because there is no true mathematical pattern to turn it into a formula.
People have been trying to find ways of doing this for years, and came up with JPEG compression...so I don't think there's a way to do it in the way I think you mean...
