Det er nu et færdigt script jeg søger med denne funktion...

Så laver du på din side:
<?php
//funktionen fra før...
$filename = "jeg_er_en_hest.jpg";
dl_file($filename);
?>

findes dette ikke færdigt?

Jo, lige op over...
Ellers må du prøve at forklare dig en smule bedre.

Jeg prøver, dette er kode til indsættelse i en side - jeg søger et selvstændigt "program" hvor man kan uploade filer. Ligesom dette her http://phpatm.free.fr/ blot med den forskel at ingen kan se den virkelige url adresse.
