A quicker, easier way to get rid of all the white in GIMP is to go to Colors/Color To Alpha and select white. The white becomes a transparent alpha channel and only the black lines will be visible.

In Paintshop Pro I just use the magic wand selection tool and select any white spot and click "select similar" and hit delete. Anything deleted on a layer becomes transparent.
