Happy Twixmas everyone (new word I just learned 2 min ago)

I have finally gotten around to implementing a gallery feature to timeline.

There is still some hiccups, like the limited caching is making it difficult to make links back to older posts not working. Maybe @eapl.me you can help me with that?
