This article could really benefit from an image DIFF widget. Even animated flashing GIF images would be an improvement.
It needs something that not only permits comparable overlays, but (perhaps with a third diff layer) also highlights the ugly/wrong pixels with a high-contrast paint.
A handful of images are only somewhat obviously problematic, but for most of the images, I really had to struggle to find undesirable artifacts.
If it's that difficult to discern inconsistent image artifacts, one can understand why so little attention is often paid to this situation.
