Image mapping with a javascript image swap

I originally posted this in the Design your Site forum but on reflection think this is probably a better place for it.

I have a javascript which changes the page header every time the page reloads. There are also images within the header that I need to have links to other sites from.
Can I combine the code used to produce an html image map with the javascript or will it require more scripting to do this.

The link shows the site logo. Ideally I want to link the facebook logo to their facebook page and their company logo back to the home page.

Any help will be greatly appreciated.
