Gradual-Highlight Image Script II-
By J. Mark Birenbaum (birenbau@ugrad.cs.ualberta.ca)

Modified by jscheuer1 in http://dynamicdrive.com/forums/
to work with Mozilla and other opacity compliant browsers
in addition to the original IE functionality

Modified and expanded by Aaron Harper (8th May 2010) to to cycle
fade/in out of objects to provide a smooth transition
