urllib implements the http protocol for http URLs, so you can only do
what the http protocol allows.  Thus if http://somedomain.com/foo/bar.jpg
is a valid URL on that server, you can do a urlopen, and then check
the 'getcode' method on the returned object to see if you got a '404'
(not found) code back.
