	Add linkbar images here. The pictures must be in
	the following format:
	File Format: gif
	Image Size: Width 150px, Height 48px
	
	The linkbar_images Array must be updated if more
	links are added to the linkbar. The linkbar in
	template.inc must be updated too.
	
	linkbar_images format:
		- only list the file name, no extenstion!
		- must reside in the images directory!
		- a mouseover image must exist too!
		
	Let's use the home_button as an example.
	- main image is home_button.gif
	- rollover image is home_button_mouseover.gif
	- both images are in the images directory
