Images in the blogroll are not visible but when you click on the individual post the images are there.

Do I have a setting not set right?

Do you mean blog posts? Because blogroll has a special mean in WP sites https://codex.wordpress.org/Glossary#Blogroll

Are you referring to post thumbnails or featured images in posts? Did you check if your theme supports post thumbnails?
