Go to https://en.m.wikipedia.org/wiki/Jebel_ech_Chambi#/image/File:Chambi1.JPG The media viewer loads a scaled down version of the entire full size image rather than a thumbnail appropriate for your screen size. Since full size images can be up to 100 MB in size, this could be awful for someone on a strict data plan.
Prioritization and scheduling of this bug is tracked on Trello card https://trello.com/c/C2Hc3nJZ
Nevermind. It actually just loads an image twice the resolution of the width of your window, which makes sense. I just happened to be using a very large window :)
