Advanced Guestbook not showing smilies or images

I have just installed the Advanced guestbook and everything seems ok apart from the smilies and images don't show up. All the images are there in the img folder. Could anybody point me in the right direction?

Many Thanks.

I forgot to mention, this is the URL to my guestbook, http://cgi.fellglint.plus.com/guestbook/index.php

Try this. http://proxy2.de/forum/viewtopic.php?t=3628&highlight=missing+pictures

Thanks JTD, I've set base URL to http://cgi.fellglint.plus.com/guestbook/img but the images and smilies still don't show up. Any ideas? This is how I have it setup.

/* misc */

define('IS_MODULE', false); /* running as POST-Nuke 0.x or PHP-Nuke 5.x addon? */

$GB_PG["base_url"] = "http://cgi.fellglint.plus.com/img";

$DB_CLASS = "mysql.class.php";
$TEC_MAIL = "";
$GB_UPLOAD = "public";
$GB_TMP = "tmp";

if ($GB_PG["base_url"] == "") {
$inter_type = php_sapi_name();
if ($inter_type == "cgi") {
if (isset($HTTP_SERVER_VARS["PATH_INFO"]) && !empty($HTTP_SERVER_VARS["PATH_INFO"])) {
$GB_PG["base_url"] = dirname($HTTP_SERVER_VARS["PATH_INFO"]);
} elseif (isset($HTTP_SERVER_VARS["REQUEST_URI"]) && !empty($HTTP_SERVER_VARS["REQUEST_URI"])) {
$GB_PG["base_url"] = dirname($HTTP_SERVER_VARS["REQUEST_URI"]);
} else {
$GB_PG["base_url"] = dirname($HTTP_SERVER_VARS["SCRIPT_NAME"]);
}
} else {
$GB_PG["base_url"] = dirname($HTTP_SERVER_VARS["PHP_SELF"]);
}
}

?>

Thanks

$GB_PG["base_url"] = "http://cgi.fellglint.plus.com/guestbook"; would be the right base_url.

Thanks very much Carbonize, that worked a treat.
