What I want is the possibility to have many photos for a product. And i need one thumbnail (but I think I'll thumbnail every photos, otherwise it'l become a bit complex to manage everything..).. So in the list page I display the thumb, in the Inspect page I display all the photos (I don't know if every photo in the same moment, or just a sort of embedded gallery in the page with next and previous button..)
I'll try this morning creating a new project and a new db connection, to not destroy my old one, until I find the right migration

I'll go for the cover method
