Londo,
That's b/c study conductor's routinely harp on the photos by asking the audience to pick out the learning points.
Like I the Jeremiah book where they show a young sister with punk hairdo/clothes being counseled by the elders. She's looking away from them with a F.U. attitude (photo 1).
(photo 2): show her looking at a field service photo of her in her goody JW days, while she sits in her run-down apt., baby in the crib, dead-beat boytoy past out drunk on the sofa.
Photo 3: she sees the error of her ways, cleans herself up, sheds a few tears of genuine repentance and is welcomed back to the congo with open arms, her daughter in tow.
moral of the photo montage: listen, obey, be bleesed.
