Når jeg prøver at uploade et billede med det her script

<?php


require_once('../Connections/skigol.php');





$src = $_FILES['fil']['tmp_name'];

$ext = strtolower(end(explode(".",$_FILES['fil']['name'])));

$kommentar = $kommentar;
$uge = $uge;
$tid = time();

$nytNavn = "Uploadet-" . $tid . "." . $ext;

$dst =$_SERVER['DOCUMENT_ROOT'].  "/prototype/upload/". $nytNavn;


copy($src,$dst);

$image = $dst;

if(file_exists($image)) {

$foto = 1;

$imgsize = getimagesize($image);

if($imgsize[0] > 200) {

$width = 200;
$height = 100;

$scr_img=imagecreatefromjpeg($image);

$dst_img= imagecreate($width, $height);





imagecopyresized($dst_img,$src_img,0,0,0,0,$width,$height,imagesx($src_img),imagesy($src_img));


imagejpeg($dst_img,  "../prototype/upload/thumbnail/" . $nytNavn);

} else {

$src_img=imagecreatefromjpeg("$image");
imagejpeg($scr_img, $dst);
}

$imgurl = $_SERVER['DOCUMENT_ROOT']. "../prototype/upload/thumbnail/" . $nytNavn;

} else {

$foto = 0;
}

$query = "INSERT INTO billeder_ski_bukser (billede, uge, kommentar, thumbnail) Values('$dst','$uge','$kommentar','$imgurl')";
mysql_query($query);

?>
