Yeah there were also some photos of little Amelia and a woman who was either her Aunt or her mum although both will make an appearance in the finale and I think these were also in a museum.
I know there are a couple of embargoed pics flying around but they won't be released for a few more days.
EDIT - Interesting fact: The apple with the face cracked in TEH looks like a smile, the crack also looks like a smile. No I am not saying the apple is the crack but it's interesting to know that Moffat once called/planned on calling the crack 'the crooked smile'. Make of that what you will.
