Sorry for the obviousness of this question but I've looked all over the ACP searching for the answer before I decided to post here looking for help and was unable to come up with answer.
My guests are unable to view attachment images, but can see url images. There is a little message in the post for guests saying that they don't have permission to view the image attached.
This is not a setting which I want. Like the url image, I would prefer that guests could see the attachments as posted, but I can't find any specific setting for controlling this permission.
