Default Picture quality with GD

I use GD in applications to enable users to upload and create pictures in a
certain size:

$img_resized = imagecreatetruecolor($img_new_width, $img_new_height);
imagecopyresampled ($img_resized,
ImageCreateFromJpeg($_FILES['strFile']['tmp_name']), 0 , 0 , 0 , 0,
$img_new_width, $img_new_height, $img_orig_width, $img_orig_height);

The quality of the resulting pictures however is not so good due to a
compression that is higher than necessary.
Anyone a suggestion for improval??

Thanks, Nico

OK That's probably better, but You can't resize a picture with that function
:-(
Thanks anyway,
Nico
