You still need to define what "well-known" is. It is because the photo can be famous on one side, while not on the other side, just like local pop songs - popular locally but not globally.

"Fantasy photos" on the other hand is a confusing term. Fantasy can have several meanings. I'm not sure if you are talking about the way you want to talk, or the photos are just all made up or hypothesized by you, or photos which give you a lot of satisfaction.
