We need a program (C, C++, VB, etc.) that takes as input 4 JPEG files. The four files are scaled and cropped according to user input, and then assembled with individual X/Y pixel adjustment into a single animated GIF file. Four JPEG files in, one GIF file out. You must know how to manipulate, scale (nicely anti-aliased), and crop JPEGs, and how to assemble an animated GIF.
