Here you can make use of the back and forward functions with pictures. All you need to do is copy this 2 lines. Just change the uppercase text. 

<a href="" onClick="parent.history.back(); return false;" onMouseOver="self.status='Back'; return true;"><img src="YOU PICTURE" border=0></a> 
<a href="" onClick="parent.history.forward(); return false;" onMouseOver="self.status='Forward'; return true;"><img src="YOUR PICTURE" border=0></a>
