$db=mysql_connect("localhost");
mysql_select_db("members_pictures",$db);

unset deletes variables, are you sure you aren't looking for unlink?

If so, you could readdir() in a loop, and check the database for the filename.

[code]        $dir = realpath("."); //current folder.
        if($dh=opendir($dir)) {
            while(($file=readdir($dh))!=false) {
                $result=mysql_query("SELECT `picture_file_name` FROM `picture` WHERE `picture_file_name` = '$file'");
                if(mysql_num_rows($result)<1) unlink($file); // no result DELETE FILE
            }
            closedir($dh);
        } else echo "directory error"; [/code]

note, this is an example script and might not work just right for you. Oh, and this WILL delete files, so be careful. Test it someplace before you load it on your production site.
