The array would have to be contiguous, which it may not be immediately
coming out of PyFITS. You also need to be sure that you are using the
right mode for the data.
In [7]: import Image
In [8]: import numarray
In [9]: z = numarray.zeros((256,256)).astype(numarray.UInt8)
In [10]: z[128,:] = 255
In [11]: img = Image.frombuffer('L', (256,256), z)
That creates a black image with a white, horizontal line in the middle.
