Alice’s 80th — pick the hero photo, hide anything that shouldn’t be public.
Click Make hero on the photo you want across the top of the page. Hide pulls a photo out of the public gallery — it isn’t deleted, and you can bring it back any time.
Finds the same picture uploaded more than once — including copies that
aren’t byte-for-byte identical, because the uploader re-encodes big photos.
It keeps the earliest copy and hides the rest. Nothing is ever deleted, and
Undo puts every one of them back.
Photos taken seconds apart — the same group holding the same pose — are
different photos and are deliberately left alone.
