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.
