Grungy photo print effect I am trying to reproduce a grungy photo print slideshow in Blender that was originally created with After Effects. Despite much searching and experimenting, I can't make my Blender grungy photo prints to look as the example below complete with all the blemishes. There are two .mov  files used by After Effects to create the effect. Can someone please give me some ideas how to replicate this effect in Blender.
Base files

By following some tutorials on transparency and bump maps plus some trial and error, I found a way to set up the Blender nodes to get the results I wanted. 
The photo in the frame is placed behind the border and adjusted to the shape of the frame.

Knowing that transparency is based on a black and white image helped me. I hope someone finds this information useful.
