I've been checking through settings, and I've been checking all over the site, but can't find a definitive answer to this question:
Does the wiki store all the images in the database, and is there an option to change this to the file system?
I can't remember if I had to set this somewhere in the early days, or not, but I know some other attachments types I had to move over from the database to the file system after upgrading to vB4, and can't work out if the same has happened between VaultWiki 2.5 and 3.0?
