nd_image was a Package that built on top of numarray and was also
distributed with numarray. Exactly what goes in the base numpy
backage and what goes into add-on packages is a question we will wrestle
with for a while.
With the existence of SciPy, I don't favor growing NumPy much beyond the
(general) feature-set it has now. There are already people who grumble
that it includes too-much stuff that they don't need.
Other functionality should be added by other packages. We are trying
to make SciPy into a large collection of packages that don't all have to
be installed, so that users can pick and choose what they need if they
must.

Not directly accurate. The SciPy version is maintained by the SciPy
developers (not by the original author).

Many SciPy packages can be installed separately and nd_image (now
scipy.image) is one of them. So, it is very easy to just install the
scipy.image package. Hopefully, more people will run with this concept
as the need arises.
And, scipy is not has hard to install as you might think. Especially if
you go into the setup.py file and comment out all the packages you don't
actually want...
