Sort images in a specified way

[Glodenox]

A suggestion was made to provide a system to sort the images alphabetically. While this is possible, I think it would make more sense to just always sort them alphabetically. People will generally not add images in a specified order, so that seems like a safe thing to do.

If we do want to go in the direction of more functions, it would be possible to sort the images in several ways that I can think of straight away:

• By date added
• By name
• By distance from current position
• By size (big to small, small to big)

But all that probably requires several changes to the UI, partially also to surface some data that isn't shown at the moment.
