How to Get my Post images to show up in Bloglovin

Hello,

I’ve added my blog to BlogLovin’ but for some reason my image is not showing up next to the post. The thumbnail of my main page is showing up, but an image of each new post should show up next to the thumbnail and title. When I tried to contact BlogLovin support (they are extremely non-responsive btw), their “help” section mentioned something about RSS feed. I’m not sure what this mean. Does anyone know how to fix this problem?

My blog name is https://www.KTRstyle.com
