Problemer med upload af billeder

Hej.

Jeg har lavet en hjemmeside for nogen hvorpå der mulighed for at uploade billeder. Det script jg bruger virker fint på min egen server(b-one.net(vist nok windows)). Men på den server hvor siden skal ligge (wannafind.dk(linux)) virker det ikke, billederne bliver simpelthen ikke uploadet. Begge servere køre i safe_mode.

Er der nogen der har et forslag til hvad problemet kan være?

kode:

if(isset($_POST['sender']))
{
if ($HTTP_POST_FILES['img']['name'] != '')
{
$upload_bibliotek = "../img/photos";
echo "upload_bibliotek - ".$upload_bibliotek."<br>";
$fra = $HTTP_POST_FILES['img']['tmp_name'];
echo "fra - ".$fra."<br>";
$oprindeligtnavn = $HTTP_POST_FILES['img']['name'];
$til1 = $upload_bibliotek . "/" . $HTTP_POST_FILES['img']['name'];
echo "til1 - ".$til1."<br>";
$til2 = $upload_bibliotek . "/thumbnails/" . $HTTP_POST_FILES['img']['name'];
$til3 = $upload_bibliotek . "/tiny/" . $HTTP_POST_FILES['img']['name'];
$size = GETimagesize($HTTP_POST_FILES['img']['tmp_name']);
