Taking photos simulation

I saw a demonstration of this technique on YouTube (https://www.youtube.com/watch?v=lXicL71uL-M) and thought it would be fun to replicate it.

The demonstration video didn’t show how to ensure that photographs are shown in the sequence they are taken. It took me a while to work out the logic using a combination of Articulate Storyline’s triggers, variables and layers, but I got there!
