 *			The document.images array is parsed.  Variables for image rollover
 *			are create for all images with names ending in '_on', '_off',
 *			'_at' and '_over' (Note: image name does not include the 
 *			file-type; e.g.: .gif, .jpg, etc).  Complementary images 
 *			(e.g.: an '_on' for each '_off') must exist in the same 
 *			source directory.
