	How this works:
	
	swap images are defined and preloaded in the loading script:
		about_over = new Image();
		about_over.src = imageloc+'about_over.gif';
		about_out = new Image();
		about_out.src = imageloc+'about.gif';
		
		Prefix the above with the name of the image to be swapped must 

		The anchor calling the mouse routines should pass the name of the image to be swapped.
