Symptom
We used pictures in the documentation field of a task, but they are not shown in the comment view.
Resolution
This behavior is to be expected, if the access to the diagram is granted with the "Invite to Comment" view and the linked pictures are uploaded in the workspace. With this function an authentication key is created that is solely valid for this diagram and not any linked sub-processes or linked pictures. Therefor the user has no access rights to the pictures that are located in the Signavio workspace. External linked pictures are displayed, when the user has access to the server they are located on.
