PNG Support in IE
One of my Featured Feed advertisers asked me to look in to supporting transparent PNGs in Internet Explorer. I found this article, added the code, and it worked.
PNG is a graphics format, like JPEG or GIF, but portable and unencumbered by patents. IE doesn’t support transparent PNG images properly. Using a transparent image, it is possible to let some of the background behind the image show through. It is a very useful technique, allowing parts of an image to take on the color of the web page it resides on.
