What's the difference between jpeg, mpeg, bitmaps (and others...) is there a best (clearest) way to store the the info?

Jpeg, Mpeg, and Mpeg layer 3 (mp3) are compressed in a similar lossy manner. Bitmaps are typically not compressed at all, or use very simple compression (such as run-length encoding). PNG and GIF use lossless compression, using various techniques.
