Re: Gallery Conversion
Have you tried the Admin -> File Galleries page,"Move files from database to directory" option? You need to set the Admin -> File Galleries "Storage:" option to "Store in directory" first, and then set the "Path to store files in the file gallery:" to the folder to hold the images. Set the permissions on the folder to 755 (or rerun setup.sh after setting the folder path, which will set the permissions for you, at least in Tiki 9.5 and older). And then use the "Move files from database to directory" option.
