The only relation between HTTP and HTML is that most full pages
retrieved by HTTP are HTML. If you're going to use HTTP to fetch the
image, *something* has to deal with generating the HTTP headers.
The best you can do is write a wrapper that deals with the HTTP
headers then invokes your program to send just the image.

You know, it's *really* hard to figure out why something doesn't work
if you don't know what happens when you try it. What happens when you
try fetching the URL for the python script directly? How about if you
telnet to the web server and do a HEAD on that URL? And so on...
