On VW3 users could user images from anywhere on vbulletin. No matter if it was from the same wiki article, another wiki article, another vbulletin post attachment, a vbulletin album, or even a vbulletin group or blog image.
When importing those images wiki article, this involves:
- vb attachments on the same article
- vb attachments on a different article
- vb attachments outside of vaultwiki forums, inside vb forums
- vb attachments outside vaultwiki forums, outside vb forums
Optimally the importer should catch all these and import those into VW4 so that the images are preserved for the wiki.
