How to install a script?
Download the Zip file and unzip it.
Move the script to the Presets/Scripts folder in the default preset location of the Adobe Photoshop application. On next launch, the script will appear in the File > Automate submenu.
Scripts added to the Scripts folder while Photoshop is running will not appear in the menu until the next time you launch the application.
Also: the Browse item at the end of the Scripts menu (File > Scripts > Browse) allows you to execute scripts which are not installed in the Scripts folder. You can also use Browse to select scripts installed in the Scripts folder after the application was last launched.
