Hi,
Maybe you can do something like this (if you have access to GD on the
server):
<?
$str_image = my_function_to_read_image_from_db($_GET['id']);
$im_old = imagecreatefromstring($str_image);
$im_new = imagecreatetruecolor($_GET['width'], $_GET['height']);
imagecopyresampled($im_new, $im_old, 0, 0, 0, 0, $_GET['width'],
$_GET['height'], imagesx($im_old), imagesy($im_old));
header("Content-type: image/jpeg");
imagejpeg($im_new, '', 90);
?>
