Success, what I ended up doing was moving all the photos/albums from file storage into the database and then making a new attachment-folder for them and transfer them out of the database into a file. After that they import without any problem. I will agree with you that there was an orphaned photos from deleted users, I don't believe vBulletin deletes the albums when a account is deleted.
I know you do not provide support for this importer. I do want to thank you for your help with figuring out why it wasn't working for me.
Have a great day.
