Each function is called using the addLoadFunction using the following syntax
	
	<!--  Begin miniScript calls   -->
	<script type="text/javascript">
	var titleHolder = '{PAGEHEADING}';
	addLoadEvent(brimages);
	addLoadEvent(classify);
	</script>
	<!--  End miniScript calls     -->
	
NB: When using functions that require the {PAGEHEADING} php include it is necessary to declare this 
as shown on the second line of the code
