Alpha channel PNGs in IE

Gifs suck. PNGs (Portable Network Graphics) are much better – more colours, freedom from intellectual property rights, and (best of all) an alpha channel for transparency. Some good articles:

- PNG opacity (with some nice examples)

- Fuzzy Drop shadows (like on Google Maps)

- Transparency with HTC files

- And again

- Choosing what image to serve in PHP on the server
