Image upload script

Hi, I found this script, about uploading images via the theme options page.

if ($_FILES["logo"]["type"]){
$directory = dirname(__FILE__) . "/upload/";
move_uploaded_file($_FILES["file-logo"]["tmp_name"],
$directory . $_FILES["logo"]["name"]);
update_option('logoimage', get_option('siteurl'). "/wp-content/themes/". get_option('template')."/upload/". $_FILES["file-logo"]["name"]);
}

So, I only can upload images if the option ID is “logoimage”. But I want to upload images with more than one ID, without duplicating the script everytime, and changes the types.

– Hope you can help ! Steven.
