Normally, all customers get to see all product images. We didn't think that made any sense at all, so we programmed this module. With this module, you can select for each product image which languages it should be displayed in.
Example:
Picture 1 is only shown to German customers
Picture 2 is shown to French customers
Picture 3 is shown to English customers
Picture 4 is shown to all customers
... This is about the language setting, not about the customer's country of delivery or billing.
So if you click on the English flag and then on the product, images 3 and 4 will be displayed in the above example.
