 * Function : prefetches images into browser cache
 * Purpose  : creates image objects for all of the images that are required
 *            by the navigation rollovers and then using their .src properties
 *            loads the .png files into the objects. 
 *            This prefetches the rollover images into the browser cache
 *            thus making them more responsive by eliminating the time that 
 *            would otherwise be required to fetch the hover graphics from the
 *            server.
