Sounds like the image was generated by some kind of server-side script. If it was generated by a PHP script that you have access to, just include a call to header(), like this:

header('Content-Type: image/jpeg');

Make sure to call header() before outputting anything—even a blank line or stray space that was accidentally output will cause header() to fail (usually it's best if you put your call to header() at the beginning of the script).

If you don't have access to the script that generated the image, then you're out of luck, I think.
