Disable images only on mobile?

I am using this plugin so I can display content inside a membership site as the dripped content feature only works when the content is added to a menu, and the client wants the thumbnails to be attached to each menu item. Works PERFECTLY on desktop and does exactly what I need it to do.

But on mobile the menus are changed to hamburger menus automatically and when the menu is expanded it takes up a ton of space with the images and leads to a bad user experience (people are complaining), so I’m wondering if there’s a way to disable the images on mobile only?
