you can also do this with mode=map as a parameter in the QUERY_STRING, 
but this has a problem in that the mime type headers are emitted before 
the image also to stdout and this will cause the redirected image to be 
broken as an image.

That said, it would also be pretty trivial to write a perl script to 
strip off the HTTP header lines. THis should assume that there are other 
lines also like cookies cache control headers, etc.
