There are quite a few people who have indicated that photography and the posting of photographs is one of their main reasons for being here. A photographer may not want to have their entire profile public, but may want to have their "photostream" or "album" available.
So therefore I think it might be a good idea. Or, if it were possible for things posted on cake, through a tool similar to ifttt, to be added automatically to a photograph storage site like flickr and for there to be some way for the Cake visitor to access the photographer's stored photos on the other site.
The point is not so much how this is implemented but rather that if this is indeed the main reason that certain people are on Cake then those who desire to interact with a specific person should be able to access what interests that person, if you understand what I am trying to say.
