if the image is just browns, convert it to rgb by right clicking on the image Image -->Mode -->RGB. now, convert it back Image -->Mode -->Index. you will get the index dialog. in this dialog you can use the "Grays" palette. if the image has more than just browns in it, a little extra work with the palette editor will be necessary. Dialogs -->Palettes will bring the Palette Palette Dialog up. Select the palette called "Untitled" and right click on the dialog. there will be a menu in which you can import a palette with. Select this and point the next dialog at your image. the resulting palette can be easily edited. you actually have what i consider a fun job for the gimp. > I'm very much a novice at this sort of thing so I'm just fumbling my way > around.
