Can't reproduce this issue. What will happen if you copy and paste the content directly into one document instead of use the insert->object->Text from file? Have you compare the size of this document before and after you save the file?Try to change the extension of this file as zip to check the document.xml file and .rels file .

Well, actually you created a outline view.
Open a new blank document, click View->Outline->Show Document->Insert, insert a document including pictures, and then click
unlink, Close Outline View->save this document. Reopen it, pictures are still here. Did I miss something?
If you mean you can't see pictures in outline view, you can refer to the thread below :
