Unfortunately, the makers of the vBGallery software is in the process of shutting down their company and will not be issuing any fixes.
I am working to find a proper alternative but there aren't many that I find acceptable. I still have all the photo files but it will take me a while to sort through the cryptic file scheme and identify who owns everything.
In the mean time, I've added a rudimentary Gallery function that uses the built-in Album feature and makes it easy to find, search, use, and share your photos so please feel free to use it.
These Albums are internal to the Forum software so there's no concern about the same thing happening to photos you put there.
