Show portrait images in carousel

Hi. I have searched this forum but can't find answer to my question. Is it possible to use both landscape and portrait images in the carousel at the same time? I have tried this but only the upper part of the portrait image is shown. Any help will be useful.

You need to stick to same size images. This you can do is to put all images graphic in same size transparent container, you can use gif or png or any format that supports transparency.
