That image is wrong and misleading.

Facebook: 140000000000 photos

Flicker: 6000000000 photos

Instagram: 150000000 photos

LoC: Wikipedia says 12000000 which is around the "Facebook has 10000 times more" so let's use that.

-----

Let LoC be a square of 1 pixel side lengths.

Instagram is 12.5 times as much. So the area would be ~13 square pixels, that leads to side lengths of 3.5 pixels.

Flickr is 500 times the LoC -> 500 square pixels -> square with sides of 22 pixels

Facebook is 12000 the LoC times -> 12000 square pixels -> square with sides of 110 pixels

Ouch.

Image is definitely wrong based on your numbers but I'm not sure it's "misleading". Your picture also shows a complete dominance by facebook. The difference is big, but not important for the purposes of the article. Especially when you consider how poor humans are at determining amounts of things based on area (see the recent discussions on pie charts).
