hi, i'm editing a scanned picture, and was wondering if anyone could tell me how to replace all colors, except black, with white....i traced over the lines on the original with my mouse, but the original scan pixels are still there. any advice would be very much appreciated.

Use the "Select regions by color tool" and click on one of the black areas. You may need to adjust the threshold setting. Then Select|Invert. Then use the Fill tool (the bucket) - selecting "BG color fill" so it will fill with white, so long as your foreground and background colours are the default black and white - by clicking the image. You should now have only black and white areas. Of course, this means *everything* that is not black will be wiped out and replaced with white.

Try "Colors->Threshold..." tool or "Colors->Levels...". Both should do this quite easily.
