Easily straighten a crooked scan or photo in GIMP

To easily straighten a crooked scan or photo in GIMP, don't bother with manual rotation and rulers. Just use the Measure tool (Shift-M) and draw a line along a straight edge or horizon line of your image. Then click the "straighten" button and it will rotate the image to match the line you just drew.
