I don't understand how to use this, it is actually setting the number of
column where to start scrolling, and it seems an image have only one
column?

Though only setting `auto-hscroll-mode' to nil let move with C-f/b and
left/right as expected, may be this value should be let-bounded when
image-mode is detected?
