We used to think that too, until we actually tried it out.  Because
of the way JPEG compresses in groups of pixels, it would seem that
you wouldn't get sharp edges.  But in fact you do.  We have no idea
why it works as nicely as it does, but suggest you try it out on
your *own* graphics before dismissing JPEG out of hand.  We're sure
glad *we* did, since PNG is so badly supported by the browsers...
