It probably is a real picture. When I was in Yeshiva in Israel I remember seeing people putting xmas tree ornaments in their succah. They were native israelis, never saw a TV, and had no idea what they were.
It’s not like it’s the first time a photoshopped yarmulke appeared in Hamodia. Just look at any advertisement where stock pictures of kids (without payos) are all wearing nice velvet kippas. I still like that Yated letter to the editor writer who bashes the paper and then signs his name “Adam West”. Guess P. Lipfschitz never had a TV as a kid.
