First you have to decide on a programming language. I prefer the C family.
Then you have to figure out how to replace the pixels in the images with
executable programming logic. Once you have figured out your exact
requirements, you will probably want to sketch out your program flow on a
piece of paper, or use Visio for a nice professional look. Then just take it
one small problem at a time, and before you know it, every photo will be
programmed.
