I was somewhat surprised at the scale. The station appears quite big compared to the sun's disk, doesn't it? These astronomical conjunctions are always useful when trying to internalize the geometry in the Solar system.

The projection from the center of the Earth is 109m/(6380+408)Km*6380Km = 102m (336ft), similar to the projection of Neptune. But the angular size in your eyes maped to the Earth surface is 109m/408Km*6380Km = 1.7Km (1.0 mi) similar to the projection of Jupiter. For objects that are far enough both calculations are equivalent, but for the size in a photo I think the second is the relevant one.
