Hello,
Sorry but WooCommerce plugin does not have the option to limit single product image height and enable cropping for it. So you can use custom CSS to limit the height, for example
.woocommerce-product-gallery.images .owl-item img { max-height: 264px; width:auto; margin:0 auto; }
or use all the images with the same height (edit images using graphic redactor before uploading them to your media library).
Regards
