How do I take a photo or image, and make it a 4 color pronto friendly icon?

I've tried with photoshop- and can't make it the right color pallette..

I've several pictures and photo's I want to add to my pronto home page and other panels... But can not make them the correct 4 colors. There must be a way to make just about any gray image look decent with dithering and the 4 colors pronto offers... BUT I DONT KNOW HOW- please help.

I completely forget exactly how to do this in Photoshop, but what you want to do is save one of ProntoEdit's default buttons as an image, load it into Photoshop then save it's color palette to file. Then on whatever color image you want to convert to 4-color load the saved palette and use random (AKA error, diffused, air brush) dithering. This is quite easy to do in Corel Photo-PAINT...

To create and use a pronto color palette:

- save a standard button to file
- load it into PSP
- save color palette (menu Color, option Save Palette)

Then you just go to Color | load pallette when you want to load the pronto palette

For best results in Photoshop Copy the entire image before changing the Mode to the indexed color palette. Then Paste the image. You'll get better dithering.
