I have an image map and I want the areas of the map to be lighted up when rolled over. However, the areas aren't retangular and some of them overlap. I am wondering how I could go about doing this without using flash? Basically, I want to have a secondary maps with areas highlighted, and a script of some sort that lets me highlight/change only parts of the image on rollover.
I'm not too good at explaining, so here is a visual example of what I want done.
Image without highlight
Image with Banks Peninsula highlighted on rollover
As you can see some of the ideas overlap each over and aren't easily sliceable. Any ideas?
