The vtkImageActor was probably just overlooked when the new connection
style was added to VTK.  It definitely should have a
SetInputConnection() method.  It's an odd class in other ways, too.
To answer the question, though, you must use the old-style connection
with it.

There isn't really anything "wrong" with the old-style connections,
it's just that the new-style connections are preferred.  If you have
to use an old-style connection, then do so, and don't worry about it
because you're not doing anything wrong.
