Using this as an example, because it's the last page I visited.

When you click on an image to bring it up, you look at it then have to close it to bring up the next image. As a minor feature request, would it be possible for us to navigate images by our left-right key? It'd make browsing through images feel more natural, as some websites have this implemented. Example of implementation.

It's a very small feature, but as more websites seem to be using this sort of thing, it'd feel a little more natural while browsing the site.
