I don't know. It seems to be a Chinese thing that placing photos on bookshelves. I have to admit, I have seen similar setting on the bookshelf of my friend's dad, he is an artist (calligraphy, drawings). Not many Chinese hang photos on the wall as American do. Just to answer questions about the photos.
