separate each image and save them with a new name

Hello, let me introduce myself, I'm Antonio, a Spaniard who has been using Photoshop [inappropriate language removed] for more than 20 years. I'm not an expert, because I always repeat the same 4 things I do, but I'm attentive to all your comments and at some point I'd like to help you.

A small question, is anyone creating tools with Python?

I would like to solve a major problem, I have scanned more than 100 letter-sized sheets where there are 3 or 4 or 5 images, I want to separate each image and save them with a new name, I think the only way would be to create an order that separates by layers and saves the spaces with the image and distinguishes the empty spaces, any help would be very grateful.

Greetings from Spain.
