Código MYSQL:

if ($handle = opendir(site_root.uploaded_images_folder)) { 
    while (false !== ($file = readdir($handle))) {  
        if ($file != "." && $file != "..") { 
            if (is_dir(site_root.uploaded_images_folder.$file)) { 
                if (!mysql_num_rows(mysql_query("select  id from galleries where name = '$file.'"))) { 
                    mysql_query("insert into 'galleries' ('name','description','order') values ('".$file."','','999')"); 
                    if (!file_exists(site_root.thumbnail_images_folder.$file."/")) { mkdir(site_root.thumbnail_images_folder.$file."/"); } 
                } 
            }     
        }
