I'm not sure exactly how tineye works, nor how close the first found date matches up with the actual post date, but Tineye shows the image first found on June 1st.
Maybe someone more informed than this anon could tell us if tineye updates monthly, or biweekly, or what?
This could be a dynamically updating image for the post, although it is a weird choice either way.
