Interesting, BUT …

3) “1846 When Anesthesia Was Discovered” - I don’t believe it’s a photograph, it looks like a painting. Besides color photography wasn’t yet invented at that time. The first color photo was taken in 1861 and the quality was very low.

5) “Abraham Lincoln; The First President To Be Photographed” - as Larry Powell points out it’s not true.

6) “Image Photobombed By A Spirit” - really? Come on! How about someone standing behind supporting the dead body who then walked away just before the flash was fired? Due to the long exposure their faint image was still captured on the photograph.

That makes me question the research behind and descriptions of the other photos.
