Bascially the problem is the fact that i'm working on a clan site and the owner/moderator of the site does not have alot of graphics or coding expience. I designed a layout and it have made it into html/css but now i'm having some problem in the scripting areas.

If you go over on this page, you'll find links to member pages for the clan members. As you can see the clan member's name is a special font. The problem now is the fact that it works fine on some pages (i.e. click this (http://neosismedia.awardspace.com/teamplayers/members.php?id=members/CHIBEARS4EVER)) but if you click on this page (http://neosismedia.awardspace.com/teamplayers/members.php?id=members/SPIKE53), though an image is generated the font isn't utilized. I have no clue whats wrong. Is it maybe because the name is too long and caps??? :s: I even tried spaces using   so I know a space was generated but for some of the names, it plainly doesn't work.

Any help is greatly appreciated. Thanks!!!!

What's the code that you are using for name_heading.php? After seeing that, we can tell you more.

This script generates PNG images of text, written in
the font/size that you specify. These PNG images are passed
back to the browser. Optionally, they can be cached for later use.
If a cached image is found, a new image will not be generated,
and the existing copy will be sent to the browser.
