If the imported member's userID did not change on import your images will all be fine.
I would install the new vBgallery 1.0.2 to the new install of vBulletin.
ALL DB / FILES:
Do backups of all database and files.
- new and old
I would use phpmyadmin and export DATA
only from vBGallery 1.0.RC3 in tables:
- I would then EMPTY
w/ phpmyadmin the same tables listed above in your New forums/gallery database.
- Import your old gallery data to the new database.
- Make sure images paths on the webserver via FTP are the same.
Should not be a big problem.
