Need Help WIth Picture - ROllover, Please Help =]

I was helping out my teacher make our web page for our school and she asked me to make a virtual tour. I want a blueprint picture of my school with all the rooms to have links on the #'s that will show the room to the right in a PictureBox. Thank you in Advance.

-I would include the picture of it but it is to large, ask me if you want it to look.
