Comment 5 for bug 1520328

In fixing this, it should be noted that you also need to test for whether the embedded image is visible to other users:

1. Share the page with another user (or with "Public" or "Registered users")
2. View the page as another user and see if the image displays properly.

A user's permission to view a page is currently tracked via several different tables, at least one of which must have an appropriate record:

 - artefact_attachment: For classic "attachments", like those on notes, blog entries, and comments
 - view_artefact: For artefacts displayed directly by selection in a block (e.g. the image block)
 - artefact_file_embedded: For images embedded in another artefact's rich text fields

The import process must populate any of these that are appropriate, in order for it to work correctly.
