To create nested frames that are evenly spaced is a real exercise in calculation. But this script will take care of all the math you don't want to do to create perfectly spaced out frames based on your specifications.
You can use square/rectangular or round/oval frames. You will first draw a selection around your subject and answer the various prompts from the script. You will be able to choose how many frames you want, how thick you want them, and then what color/gradient/pattern you want for them.
The frames will be left, flat, on their own layers so you can apply the effects you want, whether you want some bevels, shadows or if you want to paint them separately. You can also use those frames to select parts of your photo and apply different settings, like changing the saturation, or the brightness.
Compatible with PSP8 and up.
