Blog Photos Still Not showing up

Sakin, Hope all is well on your end! http://verticalrunnerbreckenridge.com/running-blogs/ I am trying to get photos on the blogs page for each blog. I put featured images on each blog page and they are still not showing up on the blogs page. I would like a small photo next to the article title. Can you please help with this! I saw some things about child themes, but I am unfamiliar with this.
