So sorry. Blog_id 8 didn’t have a featured image. Try blog_id=1. Also, how do you see the query results like that? I can’t find that in the Chrome developer tools but it would be super handy!
I was just using a random image from the web.

Maybe that’s the issue?
I’ll try your image and method. Back soon. Thanks again for your help and patience.
