Images go left to right in the gallery where newer images are on
the left and older are on the right. However, our forward /
backward buttons go the opposite direction.

I wonder if we should reverse the direction of the buttons, or is
that **even more** confusing? :)

(What do other galleries do?)

When a user attempts to verify an email address, currently we
redirect them to a helpful page telling them the result. But,
that's the only thing on the page. Let's use the messaging system
and redirect to a more standard page.
