The reality is that the ajax.php file simply needs to have some code put into it. I'm fine with hard-coding something.

if ($_POST['do'] == 'imagereg')
{
	$vbulletin->input->clean_gpc('p', 'hash', TYPE_STR);

	$xml = new vB_AJAX_XML_Builder($vbulletin, 'text/xml');

	if ($vbulletin->options['hv_type'] == 'Image')
	{
		require_once(DIR . '/includes/class_humanverify.php');
		$verify =& vB_HumanVerify::fetch_library($vbulletin);
		$verify->delete_token($vbulletin->GPC['hash']);
		$output = $verify->generate_token();
		$xml->add_tag('hash', $output['hash']);
	}
	else
	{
		$xml->add_tag('error', fetch_error('humanverify_image_wronganswer'));
	}
	$xml->print_xml();
}

Anyone who hits this section of the file more than 5 times in a minute can go goodbye as far as I am concerned.
