The neighbourhood the aircraft is overflying is just under a mile from the threshold, so that would put the camera at around 3000', if my maths is correct.
Furthermore, assuming that:
a) the aspect ratio of the photo isn't distorted
and
b) the aircraft's attitude is more-or-less level (it's a mile out on finals, so that's a reasonable assumption)
It's possible to deduce that the camera must be pointing approximately 20° below the horizontal.
Therefore, given that the camera is around 2700' above the aircraft, the horizontal offset distance must be around 7500' (1.25nm) i.e. the camera position is roughly abeam the midpoint of the runway.
