For the Homepage slider to show correctly, we do recommend that the size for desktop images is 3840 x 2160px and 2160 x 3840px on Mobile.
When switching to a mobile/small screen view there is some resizing and cropping that is done, so the image won't be identical to the desktop view.
Align the images in the middle to have them centered.
