resize images w/o sacrificing quality

basic php image resize can really make your images look bad...

I'm trying to add a JPEG image resize for my catalog. However, when I tried to use the following code. My images would look very wash out. I was wondering if there's a way to resample the size of the image w/o scarificing the quality of the original image. I'm using PHP/mySQL.

<?php
$orig_image = imagecreatefromjpeg("path/to/imagefile.jpg");
$sm_image = Imagecreate(50,50);
Imagecopyresized($sm_image,$orig_image,0,0,0,0,50,50,imagesx($orig_image),imagesy($orig_image));
Header("Content-type: image/jpeg");
imageJPEG($sm_image);
imagedestroy($sm_image);
imageDestroy($orig_image);
?>

Use imagecopyresampled [php.net] instead of imagecopyresized.
