The best way to draw shapes in GIMP is by using rectangles or ellipses from the selection tools. Once these basic shapes have been selected on the image, it possible to use the painting tools to fill in these basic shapes.
To create more complex shapes, it is better to either use a vectorial drawing software, or to combine basic selection shapes together, and draw inside these basic shapes combinations.
The easiest way to draw an arrow on a picture in a few steps is to use the GIMP free image manipulation program.
Open your image in the GIMP program, select a painting tool, click where the arrow should start, hold SHIFT and click where the arrow should point. Then repeat the operation for the two other lines of the arrow.
That way, you can draw an arrow on a picture in a few seconds and easily personalize it to meet your image needs.
