Hash the images and compare the hashes.

Hi everyone,
I'm trying to determine if 2 jpeg images are identical. The images are
screenshots taken with scrot at different times. The point is to know if
the display is working correctly. I tried to use 'diff' but without
success, probably because of the metadata included in the image. I also
tried the 'compare' command from imagemagick, but it produce an image
containing the difference between the 2 images instead of telling me if
both images are identical.
So, my question is what are you using to determine if 2 images are
identical?
I'm using FreeBSD 7.0 and I need to be able to script this comparaison
for an integration in Nagios.
Thank you,
Martin
I just tried it and it doesn't work. The hashes are different. I can't
say that I'm surprised since 'diff' is "seeing" a difference between the
two identical images.
Thanks for the suggestion
