These photos would have required max. 4-5 flights and not a tremendous effort like flying hundreds of times just to obtain fake pictures to present them as evidence for the 1904 flights.
As a note: There are 307 pictures in total (the negatives of the Wright brothers) but less than 45, allegedly made between 1903 and 1905, show Flyer I, II, III flying or resting on the ground.
