This is definitely a duplicate image. It's in all the old image archive packs, but I've lost the link to it on here.
Clearly OYP's image search feature is utter garbage and needs some serious fine tuning.
The image duplicate detector is entirely hash based; different hashes, different files. This one's filesize is twice the original, with no appreciable quality difference.
Actually this one has less JPEG artifacts than the other one. Take a few moment to compare the two.
