Help with posts

Hello,
On my website http://www.tylerslight.com I use “posts” to display important information on the home page. I use it in a slider so I can flash different content across the user screen without making them click. However, I would like to display the content (graphic) and have a link so that when a user clicks anywhere on the graphic, they are taken to the linked location. Today when users click on the post in the slider, it takes them to the “Post” page where they can comment etc. How can I make the post graphic a link?
