Last I checked, most .exe files weren't compressed, and jpeg images
could frequently be compressed slightly further by good algorithms.

Also, in the normal case for jSite, you're uploading a collection of
files as a single freesite.  In that case, what actually happens is
that any smallish files get combined into one container (like a tar or
zip file) and then encoded and compressed as a group.  So if you have
some html that compresses well, and some jpegs that compress a little
bit, and some data that doesn't at all, then it will all be packed
into one container and compressed together.
