1. There are those odd rectangles in the background

3. The top fin has an orange spot on it, no where else do you see an orange spot.

You can also see normal jpg artifacts between lines of high contrast (The fish vs. the white background)

If there are any questions, or suggestions on how this was done, or how to further it, just contact me.

I did this same process to images from a wikipedia article on the JPEG compression.

The original image:

The compressed image (compression increases LTR)

Attached is the difference map with its contrast increased. Nowhere in it do artifacts appear like in the image hihihiflcl81pig posted. I'm no image expert, but it does appear like the change in filesize is not due to compression differences. Try 5634 (The order of Dave's changing signatures) for the password on that decoding program.
