Image Comparison

Solving yet another puzzle and I find that I am needing to compare two images that appear to be the same yet one has been manipulated to contain information.  Thankfully a friend set me on the right path with this online image comparison site.  I also used reverse image search to find the original image for the comparison.  I had previously tried to solve this puzzle with nothing showing. However when I reduced the fuzz - bang! There is some hidden information.
