How to save a set of images in a dynamic folder or send them using FTP after an Order "check-out" ?

Hi!,

I've made a very simple App to take Orders from Customers.   The customer generate an Order selecting products (the product is a .JPG file) from a googlesheet table, that is working acceptable, but I need help to implement the final part of the process.  

When the Order is ready, I would need to generate a "Check-out" action to send the set of selected pictures to the Customer email, or save the sets of selected pictures in a dynamic folder, or upload the the selected pictures via FTP.  

I'll appreciate a lot any advice!.

Thanks!

Daniel
