OCAP Access
An important setting for access control is OCAP Access. OPAC stands for ‘Open Content Access Protocol’ and allows Hubzilla to make images that are generally restricted from access visible to others in posts for which access is permitted.
If you cannot see images in certain posts or comments, you should check whether the ‘Enable OCAP access’ option is activated under Settings → Privacy settings.
f there is a privacy group to which posts are made by default, or if read access to the cloud is restricted, the icons for uploading and inserting media that already exists in the cloud are only available in the comment editor if OCAP Access is enabled.
