I have GD2 installed with PHP 4.2.1 on Windows 2000 machine it has also been tested on a remote FreeBSD 4.5 machine with Apache (GD2,php4.2.1) and it failed totally with webpage found. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17737&edit=1
