Yes indeed, there is! I saw it, it's on the Promenade deck, not far from the photo gallery! I didn't use it, but I think it was 29 cents per print for 4x6. The photo gallery area is mostly on the starboard side, and you have to walk over to the port side of the ship where that machine is. It's right outside the ladies' room.
You'll have a blast! Let me know any questions you may have! If you want to see ship photos, and photos of a category 6b OPV room, Nassau and Freeport, check out my photo gallery link below..
