column image with retina resolution

In columns I use this for images with retina resolution: <img border="0" src="/wp-content/uploads/2019/02/map-1-test.png" width="70" height="70">

But how can I use image with retina resolution in the the selection: Column->Background->Image: /wp-content/uploads/2019/02/map-1-test.png
??
