Swiper-3 with portrait pictures


I apologize if this is a very basic question. I’d like to use swiper with only MD and XS screens using ‘portrait pictures’. I have no problems with the standard carousel and the picture brick but I can’t do this with swiper-3, I have always a square picture that doesn’t fill in the entire screen. Is there a way to get this with swiper-3 or should I use the standard carousel ?

Thanks a lot !
