[edit] Details
If true, new subdirectory is created in /images folder (e.g. /images/a/ab/foo.jpg) for each file upload. If false, all images are uploaded in /images folder itself.
Note: : This parameter should not be changed after the first image or file has been uploaded (or you need to move all previous uploaded pictures). It will result in php-errors (see the discussion page) if articles with the old logic try to find their pictures, since the image path is calculated and not stored in the database.
