TOPIC: Captcha problem

Hello,

At the moment i have installed JoComment 4.0 on my site. Unfurtanly Captcha won't work.
The image doesn't display.

When i call the catcha.php by http://<domainname>/components/com_comment/joscomment/captcha.php i get a error like this:
Fatal error: Call to undefined function imagettfbbox() in /xxx/xxx/htdocs/components/com_comment/joscomment/captcha.php on line 50

Does any body know what is wrong?

de2.php.net/imagettfbbox

Note: This function requires both the GD library and the » FreeType library.

Either the gd library or the freetype libraryis not installed on your server.

Thanx for your quick reply.

I see that the GD library is installed but the freetype isn't. So i will contact my service provider and hope he will fix this.
