Try
	long i ;
	i = RemoveGadget( window, gadget ) ;
	gadget.Flags &= ~SELECTED ;
	AddGadget( window, gadget, i ) ;	/* (Or AddGList(...)) */

I think you'll thus be able to get away without doing rendering on your
own (but I'm not sure if the selected/deselected images are of different
sizes: at worst you'll have to clear an area the size of the larger image
before you call AddGadget()).
