/* ********************************************************
 * Function pngIE: Enable PNG alpha transparency in 
 * Internet Explorer 5.5+ by tagName, and supports

 * Author: Neil Shah | Date: 20060810
 * ***************************************************** */
 
/* Usage Instructions:
----------------------------------------------------------
Call function in HTML doc and specify elements by tagName 
that uses transparent png images. 

Example:

<script language="JavaScript" type="text/javascript">
	pngIE('div'); pngIE('span'); pngIE('li');
</script>

Script will detect which elements use background pngs 
images and replace them with IE's proprietary filter
property.
