resizing images in gd: washed out images

[edrugtrader]

i just moved to a new server and i'm having some problems now resizing jpegs... i'm using the same code on both servers, but on a new server, the resulting jpeg image is all washed out and very bright.

here is my resize code:

global $extra_item_image_root, $new_photo;

$item_id = eregi_replace("[^0-9]","",$HTTP_POST_VARS["item_id"]);
if($new_photo != 'none') {
	$array = getimagesize($new_photo);
	$original_width = $array[0];
	$original_height = $array[1];
	$im = 0;
	if($array[2] == 2) $im = ImageCreateFromJpeg($new_photo);
	if($im) {
		if($original_width > $original_height) {
			$thumbnail_height = floor((250 * $original_height) / $original_width);
			$thumbnail_width = 250;
		} else {
			$thumbnail_width = floor((250 * $original_width) / $original_height);
			$thumbnail_height = 250;
		}
		$thumbnail = imagecreate($thumbnail_width, $thumbnail_height);
		imagecopyresized($thumbnail, $im, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $original_width, $original_height);
		imagejpeg($im, $extra_item_image_root.$item_id.".jpg");
		imagejpeg($thumbnail, $extra_item_image_root.$item_id."_small.jpg");
               }
 }

this is from my php info page:

gd
GD Support enabled
GD Version 2.0 or higher
FreeType Support enabled
FreeType Linkage with freetype
JPG Support enabled
PNG Support enabled
WBMP Support enabled

has anyone seen this problem? how can i solve it?

Have you tried to use imagecopyresampled() instead of imagecopyresized()? I havent tried it but in the manual a lot of people commented that it is very good.

try using imagecreatetruecolor() instead of imagecreate(). i think that it a new addition in GD version 2, along with imagecopyresampled().
