for some reason it is not working, can you please help me finding the error?

here's my complete php code

<?php
if (isset($_GET['url'])) {
    $max_x = 150;
    $max_y = 150;
    return loadjpeg($_GET['url'], $max_x, $max_y);
}


function loadjpeg($path, $max_x, $max_y) {
 $im = @imagecreatefromjpeg($path);
 if (!$im) {
   $im  = imagecreate(150, 30);
   $bgc = imagecolorallocate($im, 255, 255, 255);
   $tc  = imagecolorallocate($im, 0, 0, 0);
  imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
   imagestring($im, 1, 5, 5, "Error loading $path", $tc);
 }

 if ($max_x != 0 && $max_y != 0) {
   $x = imagesx($im);
   $y = imagesy($im);

   if ($x > $max_x) {
     $y = (int)floor($y * ($max_x / $x));
     $x = $max_x;
   }

   if ($y > $max_y) {
     $x = (int)floor($x * ($max_y / $y));
     $y = $max_y;
   }

   if (imagesx($im) != $x || imagesy($im) != $y) {
     $tmp = imagecreate($x, $y);
     imagecopyresized($tmp, $im, 0, 0, 0, 0, $x, $y, imagesx($im), imagesy($im));
    imagedestroy($im);
     $im = $tmp;
   }
 }

 return $im;
}
?>

thank you

good luck, I couldn't get that to work either. I know you got it right out of the php manual too.

I think you have to have the most current GD library as well.
