I've finally gotten around to improving the mobile browsing experience for my photos. There are still a few nits I might try to improve (I hide EXIF information on screens smaller than 1024 pixels in width, collection previews don't scale on the smallest screen sizes, etc), but it should be a much better experience than before. This should also hopefully help those of you who don't have very wide screens.
Let me know if you spot any problems or have suggestions for improvement.
