When thumbnail image is clicked - Should go to product, but does not

[gtewks]

When anyone clicks on the thumbnail image of my store: http://wideawake.us.cloudlogin.co/index.php/vm-store
they are shown the image in a new browser window.

this of course is not what they expect.  They expect to go to the product.

How can I make clicking the image go to the product in the same way that clicking the name does?
