How to: image field in grid with rounded corners

Hi there,

Is there an easy way to show a image field in a grid (user defined custom html, with bootstrap 4) with rounded corners. the image is easy to show with {image} in the user defined grid. just as other fields. but to show the image in style with the grid i wan’t to have rounded corners.

i can’t use <img in combination with the {image} field to use the css, so any suggestions?
