Image Sizing Question

Hey WooCommerce Support, I am working on a project that I need some assistance with in the image department.

My clients images very in aspect ratio and i was wondering if it is possible to center justify all of the images and make sure they are not cropped. They want to see the image in the center of the frame and don’t want it to pass the edges.

Without me going and replacing every image in the system with a square white background is it possible to accomplish this using some CSS trickery?

Thanks!
