Thumbnail view
Thumbnail view shows preview pictures for various file types. The size of the preview pictures can be configured via Configuration - Thumbnails, as well as several other options. In addition to the thumbnail and the file name, you can display user-defined fields like the file size, or (via a plugin) digital camera information like exposure time.
Thumbnails currently work in normal file mode, but not with archives or ftp connections. Some file system plugins may also support thumbnails now.
