default=detect
What mechanism to use to transfer images to the terminal. The default is to
auto-detect. |_ file| means to use a temporary file and |_ stream| means to
send the data via terminal escape codes. Note that if you use the |_ file|
transfer mode and you are connecting over a remote session then image display
will not work.
