 From an effbot posting on 13 Jul 2002:

'''JPEG quality 100 is overkill, btw -- it completely disables JPEG's
quantization stage, and "mainly of interest for experimental pur-
poses", according to the JPEG library documentation, which
continues:

     "Quality values above about 95 are NOT recommended for
     normal use; the compressed file size goes up dramatically
     for hardly any gain in output image quality."

(full text below):

Should probably add something about this to the PIL docs...

(As near as I can tell, so far, the last comment hasn't been followed 
through on.)
