Pomoc s knihovnou GD

Mám takovýto script:

$unique = UniqID("");
dl("php_gd2.dll");
$src = $src_function($picture);

A to mi to píše:

Warning: dl pfsockopen openlog syslog readlink symlink link leak fsockopen proc_open() has been disabled for security reasons in /3w/wz.cz/x/xfish5/forum/reg.php on line 44

Fatal error: Call to undefined function: imagegif() in /3w/wz.cz/x/xfish5/forum/reg.php on line 50

Díky za radu

* vyhod to dl(), to je tady zbytecne a zakazane
* nastav tam at misto gifu vytvari png

Díky, funguje.
