i copied the random.php from http://www.zenphoto.org/2008/01/hacks/#random-image-external-site to my zp-core - i didn't create a dynamic album - where should i find that .alb file if one exists ?
i'm also using this script
<?
define('ZENFOLDER', 'zp-core');
define('WEBPATH', 'zenphoto');
require_once(WEBPATH . "/" . ZENFOLDER . "/template-functions.php");
$randomImage = getRandomImages();
echo "<img src='". $randomImage->getSizedImage(getOption('image_size')) . "'
alt=\"random image\"\n" . $randomImage->getTitle() . '" />';
?>
