dws gives a perfect example for how to fix this problem.

For FYI sake, the reason this is happening is that you are calling your CGI from the /cgi-bin/ directory (or some other similar directory). And the web server is looking for your background image is this directory. By changing the SRC information for your image, you are telling the webserver the specific place to find your image.

Another reason for the error is that you DO have the image in the /cgi-bin/ but that this directory only allows execution, and not viewing of files in these directories.
