Use of media server + add product by code + regenerate thumbnails. Avoid generating thumbnails?

[gusman126]

I have 2 Prestashop pages
1- Main, with all the products and all the information- dominio 1
2- secondary otro dominio
Main configuration, normal, do not use media server
Secondary configuration, I use multimedia server
I add all the products to Main using CSV files and reading XML files from providers.
I generate images

Now I add products in secondary using Webservice + PHP
I add everything correctly.
I add images, I avoid generating thumbnails

Up to here everything ok
When I visit secondary page product, it automatically generates thumbnails
I don't want it to generate thumbnails.
When I look at product URL uses media server
I look at files via FTP and it has generated thumbnails.
why?
If I use media server, I want to leave the image folder empty
Some screenshots and url
