>the size of continents are inconsistent from picture to picture
Take a look this diagram I drew. From the perspective of the closer satellite, the orange region takes up the entire visible face of the globe. From the perspective of the farther satellite, the orange region is surrounded by some extra space, making the region appear smaller in comparison to what's visible. This effect is sometimes exploited in cinema, where the technique used to achieve this effect is called a "dolly zoom".

Now you might say that the effect doesn't look very dramatic in my diagram. Of course, North America is much smaller compared to the Earth than the orange region is compared to my drawn circle. This will actually cause the effect to be even more dramatic for photos of the Earth than in my diagram, yielding the drastic difference you see in here >>8906519.
