Scripts for photoshop elements need to be modified so they show on the Automation Tools menu since photoshop elements does have an Scripts menu, or
triggered by an action recorded in photoshop.
You should probably test the script before doing the modification to see if the scripts compatible with pse 11 by opening the script with File>Open
and see if it works okay.
If the script works, then we can show you how to modify the script so it shows under the Automation tools menu.
It may not work with photoshop elements, since they don't offer a version specifically for photoshop elements.
