A group of kids and a mother watch as an american girl plays on her cellphone.
You can see a family in the photo.
This one is complete nonsense. There is no photo mentioned in sentence 1, therefore we don't know if the group of kids and the mother are in a photo or not.  Sentence 1: A group of kids and a mother watch as an american girl plays on her cellphone. Sentence 2: You can see a family in the photo.
