I’d love to know an answer to this, too.
I’ve found someone who has some answer. See https://www.realestatebloglab.com/blogging-in-general/wordpress-26-a-bear-at-image-handling/
But I’m such a beginner I don’t really know where this should go. Do you adapt it in the .entry img things you’ve posted from cutline? Or should it go somewhere else?
