image mapping help, what to use for urls Options

[kelllllly]

I am trying to do my first image mapping! i am using a site so it's fine there, but i do have a quesiton!

On people's xangas where they have "review , events, subscribe" they are all customized to each person. Like clicking a link will take it specifically to their site, not just xanga. How do i make it so that the links will adjust to everyone who uses this skin. This is hard to explain but i want to put the correct url in.for example, one of my links i want to map is "yours" I want this link to take the people back to their individual sight. What url would that be so that everyone can use it? What urls do i use for all of these thigns liek reveiws..events subscribe, sign in, and everything else in that area.
thanks sry if im confusing
