[Plugin: Custom fields] Getting custom field images to work

I am trying to get custom field images to work on my WordPress site. The theme I am using is Arthemia Free.

here’s the code:

<img src="<?php echo bloginfo('template_url'); ?>/scripts/timthumb.php?src=/<?php
$values = get_post_custom_values("Image"); echo $values[0]; ?>&w=300&h=275&zc=1&q=100"

Does anyone have any idea why the images aren’t loading?

Here’s a link to the website:

Thank you!
