save_file(fname, content, None, None, is_private=1)

^ creates two files in the filesystem on the first execution. These files are named unique-name.png and unique-name91a8f8.png. The file doc gets linked with the unique-name91a8f8.png.

The save_file saves the file in the disk if it does not exist. The same file will be saved again by the File.save_file().
