The good news about jpegs is that they take up less space as saved files; the bad news is that if you open and close them a lot, they lose image detail because the algorithm for compressing the file loses information each time it's opened and closed.

OK, that makes perfect sense! I had no idea about them losing image detail, does that happen even if you made no edits to the image, just the action of opening it will make it lose some detail? I shoot in jpg (am thinking about playing with raw), then I open and edit it, put a signature on it, etc, in .psp format (paint shop pro). But since the original image is jpg, would that mean each time I opened the psp file for editing I'd be losing detail also, do you know?
