There should be a file "image.m" in your octave distribution.


----------------------------------------------------------------------
octave:68> help image
image is the function defined from:
/usr/local/lib/octave/2.0.5/m/image/image.m

 Display an octave image matrix.

 image (x) displays a matrix as a color image. The elements of x are
 indices into the current colormap and should have values between 1
 and the length of the colormap.

 image (x, zoom) changes the zoom factor.  The default value is 4.

 SEE ALSO: imshow, imagesc, colormap.

----------------------------------------------------------------------

The default colormap consists of 64 gray values. You can change this
with the colormap function.

Best regards,
	Andreas
