You have to have a piece of paper with your name and order number in the photo with the smashed pieces.
I think last year I provided photos twice and as far as I'm aware it wasn't required at the time. I think all I did was provide a photo of the base showing the edition number in my first group of photos prior to smashing the pieces.
Unless they've changed procedures again.
EDITED: I just checked my email history and that wasn't a requirement in March and June of last year.
