credo sia un problema comune a linux il codice è questo

<?
if ($larg == "" || $alt == "") {
$larg = "100";
$alt = "75";
}
header("Content-type: image/jpeg");
$im = @imagecreatetruecolor($larg, $alt)
or die("Cannot Initialize new GD image stream");
$insert = imagecreatefromjpeg("fspecialeungheria\\$fileurl\\ $filet");
$width = imagesx($insert);
$height = imagesy($insert);
imagecopyresampled ($im,$insert,0,0,0,0,$larg,$alt,$width,$height);
imagejpeg($im);
imagedestroy($im);
?>
