PNG ALPHA TRANSPARENCY IN INTERNET EXPLORER

Internet Explorer doesn’t render PNG alpha transparency properly, which is a damn shame because an alpha channel makes for all sorts of interesting graphical elements on a web page. There are, of course, several hacks around this, mostly relying on IE’s bizarre non-standard CSS implementation:

• PHP solution (with good explanation and examples)
• Javascript solution
• IE7, the comprehensive Javascript solution to IE suck

I just ended up using the Javascript one, which works fine. In the future I’d like to try out IE7.
