I love you. And just for you, according to the most recent 220 scripts I have read, photos play a giant part in revealing backstory.
It’s an epidemic.
First, it’s a technical nightmare. Even huge budgets can’t create a good looking set of composite old photos from scratch.
Second, it’s not necessary. Work your writer muscles instead of lying back on the fainting sofa of family photos on the wall in the first act.
If you write it well, we can tell what has happened from the way people relate to each other in the now.
