This may be a bit of a daft question, but here goes. I know that jpegs are a lossy format and that say editing a jpeg and saving it can result in some lost quality. As for the amount of quality lost I'm not really sure but I'm guessing you would have to edit and save a high quality jpeg many times before it visually degraded. The question I have, is does this degradation apply if you are simply copying the jpeg, say from a computer to a cd-r to another computer. I don't really think so but I just want to double check.
