Dynamic image creation for the web...

I intended to add that info but forgot...
I run IIS on W2K, python 2.4.1 and PIL 1.1.5.

If possible I'd rather separate the HTTP/HTML-stuff from image creation.
I'd like to have an HTML file that refers to a py-file that creates images 
which are returned somehow (sys.stdout or something else in memory) and 
incorporated within the HTTP-response.

Yes, I believe so too. Something like this, as suggested by Benjamin:
sys.stdout.write('Status: 200 OK\r\n')
sys.stdout.write('Content-type: image/gif\r\n')
sys.stdout.write('\r\n')
im.save(sys.stdout, "GIF")

But it does not work for some reason!? Besides, I was hoping for a solution 
which could skip the HTTP-header related stuff...
