Books and/or links not showing

For some reason the book images and links are not on the Free Book section. I am using the twenty Seventeen theme and it may have something to do with it because I cannot get any imported images to show on my product single page. I have a support request in for that but I thought I would see what you may have to say about the issue I am having here.

thanks
