I've been using this basic technique for a while now and haven't seen a resource that really shows how to do it. Thought I'd share.
I tried to make the project file as small as possible. I put the original master PSD along with PNG and JPEG layers.
I also added in a bonus project file of my favorite one, it's a bit more complicated but same techniques. Enjoy!
