Gradient Banding Problem

I have a .png image with some gradient (something like inner shadow for a 600×420 div). Under the same conditions it bands in browser while in photoshop it’s fine. Yes, i tried setting 16bit and 32bit (and remaking the shadow) mode, and every possibility in save for web and devices.

Here’s the problem: http://alelujatj.hj.cx/vcard/web/# when you set the box color to #0D0D0D. Is it possible to go without it?

I struggled a bit to notice it. Have you used what I sent you on Forrst? (nomorebanding.com)

Yes. It helps in photoshop, and thank you again, its awesome But when when I try to get it out of photoshop it’s the same.

edit: not exacly the same but very similar.

It’s probably due to browser blending transparent images. Mix 8bit color and 32bit color and you get 8bit color. If that’s the case then there’s nothing I can do here.
