[jitter] Colorchanneling with different pictures

I work on a solution to mix up picts assigning them to different channels. the result should be a layered image composed by 1pict/layer. and the picts will be read randomly out of a list, so that the content of each channel changes separately. it looks a bit like a slide show.
 
i already fixed a solution but to computed result slows down me mac, so that after a while the program crashes. is there any solution for a smoother performance.

For better understanding i will attach the file.

I'm newbie and i hope for patience.
