They all produce bad images, I have tried JPEG, PNG, as well as GIF and =
all
come out malformed. When doing a browser/cgi request the JPEG option
returns an IE "the page cannot be displayed" error, the other two =
return the
"CGI error". All three are successful in "browse" mode.

If you change your output format to PNG or JPEG, does the behavior =
