Newbie CGI Question

[davedo2]

I'm having a problem when writing a cgi script that outputs content
type: text/html. I can control the color of the screen with print
'<back bgcolor="some color">' but I can't tile the screen with print
'<back background="foo.gif">'. Is tiling not an option with Python
CGI? A push in the right direction would be appreciated.

I'm using Python 2.2.1 on Windows XP Pro running Apache 2.0.47 as
localhost for debug purposes. Thanks for any help provided.
