Images not showing on front page

Hi,

I’ve just installed Expound on https://www.haydnwilliams.com and there are no images appearing on the front page. I have set featured images for the first few posts in the list, and have made the most recent post ‘sticky’ too. I have also checked the site in another browser so it can’t be a caching issue. If anyone has any suggestions for what might be going wrong, I’d be very grateful!

Many thanks,
Haydn
