When showing an image, the URL is changed but the page title is not, which renders the browser history mostly useless. We should update the page title to something like the image name.

(The title parameter in pushState is ignored, but e.g. gmail still manages to do this in a way which works well with the browser history, so there must be a way to do it, probably by setting document.title at the right time.)
