Does Tudor Blog section allow for Thumbnail?

I have the Tudor template. I recently added a blog. I'd like to do a thumbnail photo on the main blog page to make entries more enticing and overall more appealing. I can't seem to. Yes, I did the thumbnail photo in the actual post, but it's not showing up on main blog page. Does tudor blog function allow for thumbnail photos?

Thanks

I'm having the same issue with Avenue. Has anyone solved this?

Same issue here. Can't seem to get any thumbnails to show up on the blog home page here: https://www.realmodelstories.com/stories
