Getting rid of the gray.

No, I am not talking about my hair! I have some grayscale images that are taken from a book. I want to get rid of the gray and keep just the black images (the printing.) I have in the past selected a color and gotten rid of it, but how do I select a gray tone and get rid of it?

Getting Rid of the Gray

I would just do the same as with a color image, that is, Filters-->Colors-->Color to Alpha. Of course first you would need to convert the image to rbg. You can put white to alpha and any shade of gray, or use the color picker to select an exact value. Select by Color also works with grays, afaik.

Carol's pointer was worth a look.
