The first image I found is a photo of a camera lens filter standing in a book to make a red heart. this works due to the curvature of the book and the lighting angle. The second image I found is a picture of cats whose tails line up to make a heart. The bending of the tails may mean a close connection between these animals. This photo works because the window frames the light and the rest is dark. The third image I found is a photo of a cat with a shadow of a wolf or a fierier animal. This photo works because its shows strength.
