Forum OpenACS Development: Re: xowiki, ckeditor and file storage?
The functionality of handling images in ckeditor via attachments was added after the 5.9.1 release, so make sure, you have the changes for the theme , for news , forums , or xowiki . Check as well your custom templates if applicable, whether these pass a property for "displayed_object_id". Note, that xowiki can handle embedded images also via the xowikiimage plugin, which handles images as subobjects of wiki pages and which uses xowiki image markup (with "[[image:...]]"). In the latter approach, pages with embedded images can be exported/imported in other OpenACS instances, but with the ckfinder/attachments approach, images are currently not preserved.
Concerning file-storage dependencies of the attachment package: The attachment package has essentially 2 parts: (a) an internal API and (b) a user interface. The way the attachments are used in the ckeditor packages, only (a) is used, since the user-interface is provided by the ckeditor4. The part of the attachment-description is based on the assumption, that everything works over the file-storage.... it should be made more precise.
hope this helps
