Saving Individual Pages/Spreads

I have a script that I got from someone

Window>Utilities>Scripts

Opens the script panel -

you can then right click any of them and locate it in your Finder/Windows

Edit any of them in a text editor

Paste the below code

Save it as Extractpages.jsx or something similar

Place it in the User folder of the Scripts panel.

@loicaigon I presume you don't mind me sharing this one?
