i'm creating a foto album, and want to generate the thumbnails dynamically, so i got the code below which takes the url of an image and creates a small version of it.
for some reason it is not working, can you please help me finding the error?

here's my complete php code
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 :)
