Autopsy® is a digital forensics platform and graphical interface to The Sleuth Kit® and other digital forensics tools. It can be used by law enforcement, military, and corporate examiners to investigate what happened on a computer. You can even use it to recover photos from your camera's memory card.
From http://forum.sleuthkit.org/viewtopic.php?f=7&t=43:
Can TSK/Autopsy include capabilities to do video and photo forensics? Maybe leverage the Gimp platform by having a plugin?
Something like the Amped FIVE or Authenticate from http://AmpedSoftware.com ?
