VM 4.2.12 with Joomla 3.x flattens images

[Marion]

Hi
This problem occured only after installing VM 4.2.12 and only with Joomla 3.x. With Joomla 4.x it's fine.
Images on the product detail view are not reduced proportionally and thus appear "flattened", see
https://www.ludit.ch/de/shop/spiele/dorfromantik-detail.html
or any other product detail page in this shop.
Thank you for your help!

It's caused by your template, see templates/ludit-proto/css/vm-ltr-site.css.

Hi Ghost

Thank you for your answer. You're right, I could correct it in the css-file. Strange that the same code worked fine up to 4.2.11.
