Saving under another name won't keep it from deteriorating.  Every 
time you save it as a jpeg (under any name), it compresses again, 
losing information.  If you need to work on a photo it's better to do 
it as a tiff or another lossless format.  Instead of resaving jpegs, 
start all over again with the tiff and make a new jpeg.  That's one 
reason (of many) to use RAW in digital cameras instead of jpegs.
