This script adds near-native PNG support with alpha opacity to IE 5.5 and 6. Now you can have full translucency and no more ugly grey borders! It requires only one line in your CSS file, and no changes to your website HTML. <img alt="" /> tags and background images are both supported.
A beautiful addition to any site you want IE6 compliant. I'm fond of PNG files with transparency myself, this makes viewing a site using PNG transparency possible for IE6. Update: I installed it on this site, and it's working. IE6 doesn't display my scrollwork quite right, but the transparency is working. SInce I didn't install the version that allows for a repeat, it just isn't repeating the images on the left side or top scrolls. On my personal site, I can live with that.
