There's plenty of ways to infer location information from a single picture focusing on a baby. The hospital could be identified from something as small as one piece of paper in the background with letterhead or another identifier. Or the face of a nurse in the background that was previously known to be at this hospital. Quite possibly the room layout or particular pieces of equipment in certain arrangements. Landmarks outside a window. Pictures leak a ton of side channel information outside of their subject matter.
