Question by Big Joe: How to make png image backgrounds transparent in older versions of IE?
I’m having problems, my background is transparent png image in older versions of Internet Explorer. Does anyone have any suggestions on how to accomplish this? My current site is developed in ASP code, and I’m using CSS to my page structure. I am using Dreamweaver to design my website, just in case if anyone is curious. Please help, thank you.

Unfortunately you can’t. Until Vista came out, IE didn’t support PNG files. Firefox, Safari, Opera do and have for a while.

You’d need to use the AlphaImageLoader Filter.

You may have to address the issue of which browser the site visitor is using so the filter doesn’t conflict in browsers that already have the ability to render PNGS. (At least this is what I was told, so you should confirm.) The sites above have the code you can use. After you try it you can confirm that it is working by testing your site here:

Older versions of IE don’t handle pngs well if at all…especially transparency. Give up! You might as well go gif.
