When editing an image (160.2) with a computer system, a command may be issued to display a reference image (160.0 or 160.1) to allow a human user to visually compare the current image (160.2) with the reference image. In response, some embodiments display the entire reference image in the position of the current image. In some embodiments, if the current image was rotated, trimmed, or otherwise modified in respect to its geometry, the reference image is also rotated, trimmed, and/or otherwise modified in respect to its geometry when displayed for comparison. If another image (“third image”) (610) was incorporated into the current image during editing, then the reference image may or may not be combined with the third image when displayed for comparison with the current image. Some embodiments allow the user to specify whether or not the reference image should be combined with the third image.
