Also, if you're on Firefox and on a desktop, I can very much recommend the extension Imagus (presumably, Chrome has similar extensions), both in general and specifically here, because with it, you don't even need to click to see what's disappointingly basically just a slightly larger version of the thumbnail, but you can mouse-hover over the tile and the image will pop-up full-size and full-glory!
Just THINK of all the energy you could be saving RIGHT NOW, simply by NOT CLICKING!
