I'm using JQuery Maphilight. It's very easy to set it so that the html map hotspots are highlighted on mouseOver but what I'd really like to do is either:
1) have the hotspots highlighted and remove the highlight on mouseOver
or
2) have different images appear for each hotspot (each hotspot has it's own image) on mouseover.

Are either of these possible either by editing the JQuery file or doing something else? It's important that the hotspots are irregular polygons.

The JQuery plugin code can be seen at this address: http://myklwebs.com/design/jquery.maphilight.js
