View image in full size link with imagecache (Drupal)

The solution to my problem is probably quite simple, but I can't find it. I want a link under the images saying "view full size" that links to the original, full-sized picture. I've only find the $ima开发者_如何学Gogecache_path variable that prints the path to the node.

You should be able to theme the imagecache function and add a link the original there.
