"default.img" missing in octave-2.9.13

[Henry F. Mollet]

Minor item and debating if I should even post this
but the "default.img" according to
## Load Bobbie Jo Richardson (Born 3/16/94)
needed in image.m (see code below)
is not available in octave-2.9.13 whereas it was available in Octave-2.1.71.
Therefore using "image" at octave prompt will not work in octave-2.9.13.

However, I'm not sure why providing a default image should be helpful when
using image.m and if it were not better if a warning were given that the use
of image.m requires at least one argument as per
octave-2.9.13:15> help image
 -- Function File:  image (IMG)
I have copied the default.img to where it is needed so it will work in
Octave-2.9.13 but am not convinced that it is helpful.

Second however: Whereas in octave-2.1.71 using sombrero at octave prompt
produces a warning (usage: sombrero (n)), octave-2.9.13 will accept sombrero
at the octave prompt because n=41 is assumed and then the sombrero is drawn.
Apparently an image is provided but not used in this case.
