When images are attached to a post, but don't form part of the post, you cannot view them, you need to log in for that.
Example of such a post: https://forum.paradoxplaza.com/forum/threads/missing-missionaries.1408078/#post-2675960
So yes, you need to log out to understand this error.
This happens why I try to view the image
