"secure shellfish" has some support for images, movies, etc. I'm not sure what they're using for transfer. If you ask it to, it installs ".shellfishrc" which adds a "quicklook" shell command.

It also has some integration with the "files" app to transfer files in and out of your shell session.

Edit: and I've got a cron job checking on a web site that will send a notification if has changed to my watch via the secure shellfish "notify" command.
