I'd guess you still haven't loaded the "fits" package.  If the command below 
doesnt' return anything, then its not loaded.

        which read_fits_image

To load the package ...

        pkg load fits

Now ...

        which read_fits_image
        'read_fits_image' is a function from the file 
/Users/bpabbott/octave/fits-1.0.2/x86_64-apple-darwin11.4.2-api-v48+/read_fits_image.oct
