Here, it's highly possible our fictional cat Fluffy has been referenced in our fictional photographer's bio. In this case, using his name in the photo is fine since although Fluffy may not have a nametag on, the poster has discussed him elsewhere. However, you as the viewer would not be able to tell Fluffy had knocked over the plant a few minutes ago, assuming the area was cleaned afterwards. Therefore, that's extra information that doesn't enhance the visual.
