You switched integrations and never updated your usergroups. Remember in phpbb admin is usergroup 2 but in vb3 its 6
registered users are usergroup 2 hense your dilema. You can use phpmyadmin and delete every group except admin and make the groupid 6 then refresh the groups in photopost admin to import vb
As far as userid's this is because you switched forums midstream and the phpbb userid is not the same as it is in VB
hense your pictures belong to other users. Only way around this would be to write a script to scan the vb
user table and update the userids to the proper users from there importuserid. Same needs to be done on the comments table and categories table for albums or every photo would be owned by someone else.
