If you are running vBulletin and using the albums you now have an upgrade path for both vBGallery and PhotoPost PRO. The importer for vBGallery is included in the product and we've released the BETA of the PRO importer:
BETA: vBulletin Albums -> PRO Importer
Both importers import photos and comments into their respective product and enable you to transition from the basic album feature of
vB's albums to a full fledged gallery product.
