I don't understand, the saveProductImages seems to be what I'm searching for.
But I put breakpoint in it and nothing happens, I create a new product in Back-Office and it should break where I want but the page refresh nomally.
I know that my debugger work fine so it's not the problem.
So create a product work, I can see it in Front-Office, but it looks like it never pass through the function.
I'm a bit desperate actually.
