How the id_image of the ps_image table is generated?

[[email protected]]

Hello,

I am trying to understand how some tables of prestashop work to develop my own product import software from my ERP. I generate the products and their combinations, the categories, features and other options, but when I get to the table of images I can't understand it.

In the ps_image table, the id_image is what determines the path of the image, that is, the id_image 123 tells us that its images are stored in the path img/p/1/2/3.

But when we get to image 1234, there are no more images in the path img/p/1/2/3.
What about id_image 123?
Are the files reassigned and moved to another folder?
