1) Picture - The alleged Flyer I 1903:

2) Video - A replica of Flyer I 1903 (Wright Flyer 1st Full Taxi test at Flabob Airport, Published on Sep 21, 2012, Pilot at the Controls Fred Culick):

(see min 1:44)

It is quite evident from (1) and (2) that the so called replica has the front elevator placed at a visible greater distance from the wings than in the case of the original. The bars linking the main wings and the front elevator are arranged in such a way that the replica seems similar to the 1903 Flyer. In reality the reproduction has the elevator as distant from the wings as in the case of latter planes which flew starting with Aug. 1908. They altered the pitch stability. They are not building a Flyer I but a kitsch.
It's not clear whether you're trying to impugn the Wright brothers, or the replica makers with wrightflyer.org, or both. It is clear, however, that you're trying to "scientifically" compare distances based on wild extrapolations from differently foreshortened images. You're comparing apples and oranges.

In particular, the 1903 photo has a completely different perspective than the video view at 1:44. You can easily see this is so by looking at the vertical spacers connecting the upper and lower wings.

Moreover, if you compare the 1903 photo with a video frame that acutally has a similar perspective, you can see that the two flyers appear to have the same dimensions. The video frame at 1:48 isn't perfect, but it's a MUCH fairer comparison than the frame at 1:44.

Here, just to make it clear, I made an animated GIF just for you. Have a look:
