		This set of event handlers crashes the script if the id does not exist on the page. Therefore it's wrapped in an if statement to sense if the rollover image is present.
		The event handler grabs the ids of the rollover images and monitors their activity sending the image to swap into the rollover() function.
		
		New rollover images, simply need to use name="rolloverImage" and duplicate the if block, modifying it for the id and the image to swap.
		Since there's a lot of repetition if we add more calls, it may be possible to build two or three dimensional arrays that indicate the id, mouseover and mouseout images and looping through. This may also be a case where the event handlers would be better added in a page specific file.
