bar graph gd

Hi guys: I'm using php5 on winxp with IIS. I'm trying to run a simple bar graph demo found it on phpbuilder site. When I run it I get nothing but an x in the top left corner of my web page(no errors nothing). GD is uncommented in my php.ini, ext dir set and I have verified that GD is installed through php -m,phpinfo() , and gd_info(). Can anyone offer me some advice on how to troubleshoot this problem. I searched google, and did see other posts like mine but no solutions. Any thoughts or suggestions would be appreciated.
