I have a modified version ...

  http://www.bitter-almonds.com/comp/src/perl/similar-image

... of ...

  http://www.stonehenge.com/merlyn/LinuxMag/col50.html


... (written in Perl) that asks which files to delete when digest
checksum are identical. Else, props ImageMagick window[0] with
similar files shown; after quiting that window, asks about which
files to remove[1].  (The removal can be made automatic at least in
case of identical file size and checksum, if one desires.)

See the stonehenge.com URL for background.


  [0] Press "space" key in ImageMagick window to navigate to the
      next set of images for visual comparison.

  [1] The numbers on console|xterm have 0-based index, while
      ImageMagick window has 1-based index. Yes, I need to fix this.
