i have some code that does this.. you'll probably want to clean
it to suit your own purposes, but here it is. at some point i
wanted to add PIL support to resize the images to a certain
resolution and convert them to be JPG, but that day hasn't come
yet... heh. note it also allows the user to save a comment as a
.TXT file. anyways, you can use it as a start for whatever you want

(hopefully formatting doesn't get destroyed over news...)
(warning, this is one of my very first python scripts, it
may not be 100% kosher, but it has been working well)

two files here, one is most of my cgi script, other is the
page with the form that calls the script...

# where to email upload reports
email = "ACCOUNT at server.com"
# sendmail will email notification of uploads
