You just put these codes in your header area.
Code:
<img src="the picture you're using" usemap="#mymap--the title of your map">
Next you have to make your map definition. For each "hotspot" you need 4 numbers. The hotspot is the specific area of your image that you are linking to another URL:
1st Coordinate: The upper left column of your hotspot.
2nd Coordinate: The upper left row of your hotspot.
3rd Coordinate: The lower right column of your hotspot.
4th Coordinate: The lower right row of your hotspot.
You then put this into the same area.
< map name=mymap
< area shape=rect (for rectangle) coords=??,??,??,?? href=link
</map>
(With the > and no spaces, for some reason it wasn't working for me to put it here)
