Force image size on WP custom field

I want to force the images smaller to the width="128px" height="78px". They are being pulled in with Wordpress custom field.

HTML

     <?php $description = get_post_meta($post->ID, "project-thumb", $single = true);
if($description !== '') { echo $description; } ?>

For working example: Rollover to the right of the screen, (need JS enabled)and notice the oversized image http://www.warface.co.uk/clients/warface.co.开发者_JAVA技巧uk/the-london-police

Have you tried calling the image by its URL and running it through the free timthumb script?
