Making part of an image links

I have a nice header image and im wondering how I can make only certain parts of it links, such as at www.mxtabs.net ?

Thanks

use an image map, I think there's a tutorial of how to do it on www.w3schools.com

or an accessible version, since image maps by nature are not accessible:

Thanks guys Ill try that.

I love these forums...
