Vertical image height

I’ve been changing slider settings but I can solve how to have both vertical and horizontal images in the same proportions.

With default width 1000 and height 500, vertical images are cropped. If I increase custom height, horizontal images are cropped. With auto height, vertical images are too big. I’ve tried every combination with no succeed.

So how to have a slider with same size for vertical and horizontal images but they auto adapt so they don’t get cropped

Thanks
