I haven't been able to do the combining in photoshop, but theoretically
it shouldn't be impossible. The thing would be to create postscript files
with multiple layers of bitmapped pictures on top of each other. It would
be a help if one could do it automaticly, on a click of button. And it
should be as predictable as mounting in pagemaker.
