If you start pse 12 with the internet already on, eventually you'll see some little Blue triangles at the top right of the different patterns, frames and graphics.
Then open an image and double click on the ones you want and you should see a dialog saying Downloading Asset.
Unfortunatly, you have to do this for each one.
Okay, now I see them, these extra ones weren't there when I first opened the program. Thanks!
