Ah ok, this makes things clearer for me. So I think I will start with
never- (or very late) expiring and see how soon I need more space. Is it
a problem to manually delete some of the images? I guess that they are
just directories that can be deleted without any constraints?

After this I can think about an expiring script that either sets the
Expire-dates or deletes the images itself.

Thank you for your answer,
