Ok so what is the right path for GD to be in?Fantastico never installs things right, it always breaks something. Your best bet is downloading the zip file from here and installing it manually. If that doesn't work, look for a file called something like 'config.php' or 'setup.php' for the path to the GD library. The GD library is used to make the thumbnails via PHP, unfortunately different installs of it end up in al lsorts of directories.
