Hi All, I am testing some GD functions, but I'm getting "undefined function" errors. I checked php.ini and changed ;extension=php_gd2.dll to extension=php_gd2.dll The php.ini file contains: extension_dir = "c:/php/ext" and this directory does contain php_gd2.dll (version 5.2.0.0) I am using Windows XP, PHP 5.2.0 and IIS 5.1. The function getimagesize($filename); is okay, but imagecreatetruecolor($width, $height); says "undefined function". I would appreciate some hints. TIA, Cor
