// Purpose:	To control the display of "new" image(s) on a page. The control is 
//		achived by setting an expiry date which is passed as a parameter to 
// 		this function. Any date in the past will not display the link. The 
//		following code is to be added to each location where image is required:
//		<script>checknew("6/01/2001")</script>
// 		
// SYNTAX:	checknew(date)
//		date =	standard date in the following format "mm/dd/yyyy"
//
// Examples:	checknew("2/5/2002")	will display images until the 2/4/2002.
