Situation: I am sitting on the only chair in the room and facing the table.
Alternative situations: I was sitting in the chair against the wall and there were chairs to my left and right. Relaxing on a chair between two office chairs and listening to a girl on the office chair in front of me complaining about her life, while the noise from a window in my 10 o'clock direction is getting louder.
Question: Is the picture on the floor or on the wall?
