Image Steganography (cont)
  Observations:
  Image files are generally large, and can hold large messages or hidden images.
  Encoding will result in blurrier images - works best in natural images.
  Messages usually lost during format conversion or resizing
  High number of similar colours could indicate steganographic manipulation.
