Have the observer look at the subject through a system of mirrors so the light takes longer to reach them than the camera. The extra distance needs to be longer in light-seconds than it takes to create and show them the photo in seconds.
Then the picture is from the last, and the image you see in the mirrors is from a past before the image.
Technically, everything we see is from the past. We can’t actually see the present. The further we see, we look further to the past. Things like lightnings we see in the wild happened some fractions of a second before we saw them, for example. Useless trivia but I like it.
Yeah sure, but the task was to show someone a picture that is older, not one that is not from the past. That would require some sketchy technobabble at least.

Technically the picture of a twitch streamer is from a more recent past than what they write in the chat since that chat usually has a delay.
Sometimes they even read comments that aren’t even in my chat lmao.
