So long as it provides you with a graphic, the creation of link spots should not be difficult. There are a number of applications out there that allow for the creation of imagemaps, which is basically what you need/want.
If you wanted to get fancy, you could even put the biographies into different layers, and have the clickable link run a javascript function which makes that particular layer visible, while hiding the rest. Or even have it do it on a mouse-over event.
