If its a image, no matter what it identifies as, you have very less option to validate it. You could use the bitmap checkpoint with a tolerance, but i am not sure if the data validation would look good and moreover, it is not the right way to do it. Audio, video , pics, print, scan are few which cannot be automated and are best done manual.
