Are my Photopost images saved? (Database question)
 

Last year, we closed down our website, but not before saving the vBulletin database. The forum is now restored. Now, during the Photopost and Reviewpost installations, I opted to have both Photopost and Reviewpost integrate to the forum database. So my question is this:

If I upload and reinstall Photopost and Reviewpost, will the images and products come back upon the restoration of these two applications or are they gone forever?

Did you save both your photopost and reviewpost databases as well as data directories for those applications? If you did not then no things would not be saved. Your category names comments photo entries are all stored in the database and your photos are physically stored in the data directory on the server.
