We had to reinstall our WPMU installation. We renamed the old directory. Installed WPMU in a directory named the same as what the other installation was originally in. Then pointed the new installation to the database of the old installation. Everything is functioning great except the images within the posts are not displaying. I assume I need to copy the images from the old installation to the new, the problem is I can't find them. What directory does WPMU store its images in?
