The sheer size of a jumbo is making these pics look more incredible than they really are. Note that in all of these pics so far except maybe one, the 747 is more than 100 feet off the ground still, even though it looks lower. The one in the picture that started all this appears to be at about 75 feet approximately (I judge this by the height of the vertical stab). I obviously dont know if the pic is real or not, but I suspect that it may be.
Note: as to the girl not putting fingers in ears, besides the fact that she is much further away than she looks, the noise of a 747 isnt all that much at low power settings, or idle. Now for takeoffs, you can bet that everybody around would probably have their fingers in their ears in that area.
