Sorry I have missed this post for so long... but here is what you should do to get it to work with thumbnails...

random.php should be:

<? 

$images = func_query("select * from $sql_tbl[thumbnails] ORDER BY RAND() limit 1");
if ($current_area != "C" && is_array($images)) {
	foreach($images as $k=>$v) {
		$images[$k]["type"] = (eregi("gif",$v["image_type"])?"GIF":(eregi("png",$v["image_type"])?"PNG":"JPG"));
	}
		
}

#       
# Get thumbnail's URL (uses only if images stored in FS) 
#  
if ($config["Images"]["thumbnails_location"] == "FS")
	if ($current_area == "C" && is_array($images)) {
		foreach($images as $k=>$v)
			if (eregi("^(http|ftp)://", $v["image_path"]))
			# image_path is an URL
				$images[$k]["tmbn_url"] = $v["image_path"];
			elseif (eregi($xcart_dir, $v["image_path"])) {
            # image_path is an locally placed image 
				$images[$k]["tmbn_url"] = $http_location.ereg_replace($xcart_dir, "", $v["image_path"]);
			}
	}
print_r ($images);
$smarty->assign("images",$images);
?>

and randoms.tpl should be:

<a href=product.php?productid={$images[0].productid}>
{if $images[0].tmbn_url}
[img]{$images[0].tmbn_url}[/img]
{else}
[img]../product_image.php?imageid={$images[0].imageid}[/img]
{/if}
</a>

Basicaly all I changed was the database table that it was looking at, changed the config variable (to check where the thumbnails were stored) and changed the array variable used in the template.
