I've another question.
Doing experiments with image posts. Got a post in Italian, and added an English translation.
I've seen that even if I can't use images from "Italian media library", the post thumbnail for this translation is the same of the original post, even if I changed the top most image in my translated post.
But If I remove it, I can't add it any more. I have to upload it again.
This behaviour seems strange to me, is there a reason for it?
