Bob. Hi again.  I was considering using gzip on images too, but it turns out
that images do not need to be gzipped.  For one, they are already compressed
and would not yield much savings (Same thing happens when you put an mp3
file in a zip folder).  For two, most browsers do not accept gzip images.

proper cache control:
