Posted this in /qresearch/ and got directed here. I was looking at the 2 flags in Q posts 3908 and 3983.

Same dimensions, and imagemagick even reports the same visual "signature" hash for the images, but they have different file sizes and checksums.

What I found was interesting was the SHA256 hash of the most recent image (3983) is the filename of the image in 3908:

sha256sum AMERICA.png

f768deaef22da979abcfb73c9175b54d71fcf891666c5449c1969c07c3cc8920 AMERICA.png

Post 3908 filename: f768deaef22da979abcfb73c9175b54d71fcf891666c5449c1969c07c3cc8920.png

My theory is that the key to decrypt an image is contained in a previous image. But I'm not sure how to take this further.
