Details:

When you install the current image package 2.4.1 under the current Octave dev
version (default branch in repository, 4.1.0+), then you get a couple of
warning messages. I think they are all related to a deprecated length()
command in some C files:

I observed this behavior with a current mxe-octave version of the current
Octave "default" branch under Windows 7. But I assume it will be the same 
under Linux as well.

This isn't a bug of the image package, yet. But I guess it would turn into a
bug (or at least into an unwanted strangenesses) as soon (or late) as version
4.2 of Octave will be released.
