I would suspect that the JPEG compression in Superstor 3.0 is probably
a separate utility, rather than built in to Superstor. JPEG image
compression is very computation intensive. I doubt that it is even on
the same order of magnitude of the Lempel-Ziv algorithms that Superstor
and Stacker use for realtime data compression.

From what I understand JPEG also uses some lossless compression
techniques and that if you want to you can use it without losing any
image quality, if you don't mind not getting as much image compression.
