IE6 PNG Fix Not Working?

Here is the site: http://summerbeachsandals.com/

I’ve used a couple different PNG fixes, none of which have worked. At first I tried this Javascript fix: http://homepage.ntlworld.com/bobosola/, but it didn’t work. So then I tried the one here: http://bjorkoy.com/past/2007/4/8/the_easiest_way_to_png/

That’s what I have on the site at the moment, but according to someone who just checked it in IE6, it’s still not working.

Apparently, this latter fix is from the Apple Mac Pro site: http://www.apple.com/macpro/

If you take a look at their site they have a couple PNG images on top of a background image. I’m not sure how they did it, but I’d like to use that same fix or if anyone knows another fix, please let me know, thanks.
