Try to set up ssh in such a way as to list the contents of a
directory, e.g. the directory which contains the image.

Then a simple
  % ssh user at some.host ls somedir
would tell you all you need to know.

Please refer to ssh documentation, on how to avoid having
to use a pass phrase everytime you want to access a remote
host.
