I took old family photos once to a therapy session and it ended up being one of my best sessions ever. We looked at them and talked about what was in the pictures, impressions based on them, and stories. I also enjoyed being so close to my therapist physically to view the photos (I was sitting on the floor next to his chair), it was in a period when I was very fond of him. I think that looking at pictures can also help to engage both T and client in a conversation.
