Does the integration with SharePoint 365 allow picture files stored in SharePoint to be link to a diagram element and be embedded in a process documentation? So that the report reproduces the image within?
The images from SharePoint can't be embedded in the process documentation. You can create an attribute in which a link to it will be stored or you could upload the picture from SharePoint to Signavio and then you would be able to embed it in the documentation.
