Am I supposed to see photos?

Thanks for reporting. We had some extensive cache, and the image URL got invalid. We have fixed the issue ?? Will work fine now

Then I’m definitely intrigued why my images aren’t showing at https://socninja.fmarv.co.uk/

Hello @deargeek
Go to Settings -> Facebook Settings and then clear the cache, and then clear your site cache. Facebook sometimes make the image signed links as invalid and that’s why sometimes it could not load the images.

Also You can reduce the caching time.

I’ve tried that, and with different pages.

I’ve even tried a brand new test site at https://instawp.com/
