still 1 line of code though to test for it and use if blank and there..
if (extension_loaded('gd')) ?
anyway, i see what you mean by preventing NEW gallery forums from being created, but peeps move sites to new servers etc.. or the config.inc.php gets wiped from a lock_and_write hole..
in those cases, more often than not the 1 liner can prevent this..
i guess it's a philosophy dealio
