I have an image that is 2 colors, black and white. I want to change all the white pixel to transparent. How do I do this?

Add an alpha channel to the image (if not possible, change image mode from indexed to RGB first) Select by Color (selecting white)
Ctrl-K to clear the selection
Save in a format that supports transparency (i.e. NOT jpg)

Filters -> Colors -> Color to Alpha

Hi,

I would copy the layer, paste it into a layer mask (add layer mask->from selection), and invert the mask.

Cheers, Dave.
