SFU Library does not require a specific citation style.
imagemaps are made by defining each of the hot areas in terms of their x and y coordinates (relative to the top left hand corner).
With each set of coordinates, you specify a link that users will be directed to when they click within the area.
It's tricky, because the default template uses an image as background not foreground, and you can't use an imagemap with that.
Here's a quick hack for making it possible: Find the file /wp-content/themes/default/and open it in a text editor.
