This is on an iPhone 5 with the latest iOS/Chrome installed.  The white area at the bottom only appears when viewing the gallery in portrait mode, in landscape it is all black.  It seems possible that the white space at the bottom I'm seeing is due to the iPhone 5's taller screen?

Can I direct message you the URL and login/pass to access it somehow?  It's not public.

The viewport change did the trick for me, but I'm still seeing what looks like a white bar running along the bottom of the screen in Chrome on iOS.  Otherwise the gallery looks the same as Safari.  Anyone else getting this?
