Register globals is set to OFF, which is good unless your script
previously relied on it being set to ON. To access the values use the
super global $_GET:
$first = isset( $_GET['first'] ) ? $_GET['first'] : '';
$second = isset( $_GET['second'] ) ? $_GET['second'] : '';

Is the error a PHP error or a browser error? You can do any PHP code you
want in an image generating page.
