Perhaps I shouldn't talk since I don't know diddly about the JPEG 
algorithm... unlike for, example, LZW (Lev, Zimpel, Welch/Wegman) which 
I know in excruciatingly painful detail.

However, I have to admit to some skepticism about the praise for the 
superior image quality of some implementations.  Performance yes, but it 
seems to me unlikely that there can be significantly different quality 
implementations and still have the data be recognized by another 
implementation of the same algorithm.

However, I'll be happy to be shown incorrect and that I shouldn't be so 
cavalier about which app I use to store a JPEG.
