What do we call a picture of a picture?

Is there a word for a picture of a picture? Had a search on onelook but couldn't find anything...

edit: sorry maybe I wasn't that clear the first time -- I mean like a photograph of a photograph...

Solution 1:

What are we talking about here? It seems to me it could be one of three things:

1. A printed copy of an original. That would be referred to as a 'print' e.g. 'An L.S. Lowry print'

2. A photograph of a picture. The best term seems to me 'Photo of the Mona Lisa'

3. If you are talking about another artist's copy then I think you would say 'another artists copy of The Last Supper
