I agree that call_image itself is probably identical to
a corresponding call to a linkimage'd routine. However,
I seldom have standalone call_image statements floating
around my "main" IDL program, because they look ugly,
and for portability/reuse purposes I find it better to
plug those calls into wrapper routines. Hence a tiny
overhead.

Just to clarify.
