Make A Jpg Clickable To Another Section On The Website?

i downloaded a Facebook Page template recently. the template works great, but i wanted to add one thing.here is the demo of the code:

here is where you can download the template: http:[url]....anyhow, the part i want to change is the link that directs it to the content. for example, when you scroll over About Us, the little pop up from the bottom comes out. when you click it, it takes you to the About Us content. what i wanted to do, is make it so that when you click the whole jpg, it can take you to the content also. i noticed that the small link that pops up is too tiny and people get confused on where to click.
