Software failures are processed by categorizing images associated with the failures into groups based on similarities in the images. The categorizing of the images may be performed by a software failure analysis tool. The images may include full or partial screenshots of a computer at the time of the software failure. An image may be part of the output of a test, or may be part of a report of a software failure from an end user of the software. The software failure analysis tool may be part of a larger software test management system.
