I have a database with 12000+ products, but none of them have its image set. I want to make a mass import to set an image to every product. The problem is, in order to import an image, I have to encode it first to binary format (base64) and the result put it in the csv/excel file. Of course, this is no issue when it comes to a few products, but for thousands of products, it gets tedious. I know there are a few systems that allow to import images using a url. Is there any way to mass import product images using urls instead?  Preferably without using third party modules or Python scripts. I'm using Odoo V10, running on Ubuntu 16.04.
