use an image map lol i just gave out the link to someone else i think it's
www.lissaexplains.com and then search for "image map" and click the first one, it gives you a tutorial. you don't have to like split the image up or anything (unless you want to)
if you want to like split it up and link separate images...then you can just use this really easy code

it's not that hard and you can like put gaps and stuff though i think an image map would be easier...i dunno i'm not realy sure what you're asking but i think that's it.
