Sounds like when you reinstalled, PHP wasn't compiled with GD support. You can check phpinfo() to see if it lists the GD module, function_exists('gd_info') or open your PHP.ini and search for the following:


[PHP_GD2]
extension=php_gd2.dll


If you don't see that, then you don't have GD, which means you don't have imagecreatefromgif()
