multiple disjointed image map rollovers on one page

I have three floorplates that I need to have disjointed image map rollovers.  Each rollover floorplate image with be in a different spry tabbed panel.  How do I go about breaking up the code so that the javascript can be used for different the different floorplans?  Below is the code I am using which works for the single image map.  Any help is greatly appreciated.  Thanks!
