Correctly handle PNG transparency in Win IE 5.5 & 6.

http://homepage.ntlworld.com/bobosola. Updated 18-Jan-2006.



Use in <HEAD> with DEFER keyword wrapped in conditional comments:

<!--[if lt IE 7]>

<script defer type="text/javascript" src="pngfix.js"></script>

<![endif]-->

The code has been modified to ensure compatibility when using side by side with swfobject.js



- Main code moved inside an object to avoid global variables.

- Using window.onload event, you should remove the defer keyword from the script tag.
