Hello,
You can use your images in two ways: as a background and as an image element.
When you use an image element you can not insert any text inside. It will be just image and it will be scaled on different devices.
Background image allows inserting text and other elements as it is just covered the row. The background image would be cut on mobile.
You can set background-position center center
in Woodmart Extra https://prnt.sc/ln01to Enter the row or column setting and find this tab.
This is the nature of responsiveness for images our theme does not influence that
Best Regards
