The problem with the use of this image to prove your point is that it is taken with a wide-field, or fish-eye, lens. The edges of the solar panels in the picture are in actuality straight, but if you hold a straight edge up to this image you see that these straight edges evidence a pronounced curvature, thus the curvature of the earth's limb is greatly exaggerated.

This opens up a can of worms about the apparent straightness of lines. Although we can readily perceive straight lines in our surroundings, the actual projection of a straight line in three dimensions onto our visual field is curved, except in special circumstances, but the brain compensates for this and we perceive that a straight line is straight. It is also the case with straight lines projected onto photographic images. The image above demonstrates this in an exaggerated form.
Thus, you can show a curved horizon from an altitude which is too low to perceive such an effect:
And if you orientate your camera so that you have sky in the centre of the image and the horizon and ground towards the edge, you can get the horizon to apparently curve the wrong way:
