问题
Call me crazy, but I'm optimizing a website for the Internet Explorer Mobile 7. My main problem, besides several CSS issues, is that it seems that this browser displays 24 bit PNGs in 8 bit, that means gradients look horrible.
Anyone an idea how to fix this?

You need to dither the image so that it renders nicely.
Here are two links that show you how to do this:
- Photoshop action for Windows Phone 7 Dithering
