If you ever tried to display a png-24 with alpha transparency on msie 5.5 or above, you must have noticed that image no longer remains transparent. A dark blue-gray background is rendered instead of transparency, which makes it look so ugly. This problem is only with IE.
The solution for this is the PHP code available here.

This is a common problem faced by many web designers and web developers. As web technologies progress, web developers want to take advantage of them to make it easier to implement design elements that would otherwise be quite complex - or impossible. However, if popular web browsers don't have these technologies implemented correctly, designers and developers become frustrated when they aren't able to use the best solution (or only solution in many cases) for their problem.
Can't wait to try it.
