If a page or an article used multiple editorial images ('img' objects) that were all created from the same original image (via crop for example) and the archiveUseOriginal option was enabled, the archiving failed because the same image was linked more than once to the archived document or story.
The wf_Archive is fixed to prevent the archiving failure.
Note that the fix means that an archived document or story can have less linked images than the original page or article, due to the elimination of duplicates.
This setting is in Config\Global\GN4\wf_Archive.xml.
