Warning: This installation does not support the GD extension. TFT requires this extension to be able to create thumbnail images. If you can change the php.ini file for your PHP's installation, you may be able to enable the GD extension, usually by removing the ; (semicolon) on the line that contains the string extension=php_gd. If you can't or choose not to enable the GD extension, set the $gd_available option in your config.inc file to false, to remove this warning.
