Interestingly that page never stops loading for me and drives Chrome nuts. It keeps loading tons of different images and the icon for stop/refresh alternates between the two states a couple times per second.
I saw that too. When looking at the Chrome developer tools you can see a bunch of stuff being loaded.
Something weird is going on with the favicon for me (Chrome 25.0.1323.1 dev-m). It's kind of flashing/glitching. Anyone else?
I whipped up something similar in Go recently. There's no README yet, but it uses cgo to link to ImageMagick for resizing, and serves up a folder of jpgs.
