If a court decided that it was a different work (IE: Not derivative of the original piece) and you make an exact copy of that piece then yes, that's copyright infringement. If it's so different that you'd never have had that idea on your own, even if all the component pieces are your photos, the arrangement of them is not. If the piece is so similar that you could accidentally replicate it by, say, printing your photos on one page or some shit, then the original court would likely have not found the piece to be sufficiently different to warrant its own copyright protection. God, I'm not even a lawyer and that seems clear to me.
