Hi there,
You can retrieve them if you login to the relevant language (BEFORE you login you change the language by selecting the relevant flag) and then you can find all banners in your account options.
i.e. if you want the French banners, you go to the French flag, login with your affiliate logins, go to your account options and select the French banners that you want from the product that you prefer. The same goes for all languages we have available on our site.
