I am the author of nd_image. In my opinion the package should remain  
in SciPy, where it indeed belongs. The only reason it was in numarray  
is that there was no such thing as SciPy for numarray.

Although it is relatively bug-free and has a reasonable amount of  
image processing functions, it could stand a lot of improvement.  
Including it in a base NumPy package would be a mistake, as it is not  
a fully optimized and finished package.

nd_image should install easily as a separate package, hence it could  
be included in SciPy while maintaining the possibility for standalone
