The way you can tell if a jpeg photo has been photoshopped is looking at the jpeg blocking. A sudden change in blocking is clearly seen in several places on the last photo. Half way up, about a third way from the left, there are three trees. Zoom in close (windows photo viewer will do) to those three trees and you will see a large block edge just above them. That is a jpegged image that has been laid down over the regularly distributed jpeg blocking. The photo has been edited. Jpeg blocking will not show over a smooth transition of colour. It does there. Photoshopped, QED.
