Post slider, change aspect ratio

Hi, is there a way to change the aspect ratio of the post slider images? I have a slider showing book covers, and I would like to try a higher / narrower aspect ratio to avoid cropping top/bottom.

(Plan B, is there a way to choose the crop section for individual post slider images?)

Hello,

Hello, thank you for the link.

Your book covers have different aspect ratio, you can try to make it the same.
