// super slim image preload and rollover script
// preloads any number of nav images named with the convention 
// nav_title_0.ext and nav_title_1.ext for off and on states respectively.  
// No need to name the files specifically!  Also requires much less code within the
// link tags themselves.  Specially modified for ProMedia.travel
