Large image not displayed

[pyladune]

I try to display a large image when opening a product page.
I configured the iéage settngs style attribute in the addim interface but still when opening the product page in front end, i can see no way to display a large or even original size picture of the product. the largest displayed have is the small one inside the circle, so no way to figured the product in details

According to documentation setting the style to large shoudl solve that...or there is something i did not catched

Thanks
