| Great I can now show images. However, the images doesn't appear to be

I'm not sure of the proper way to fix this bug.  I suppose imshow should
set some property to say that the image is greyscale instead of color,
but I'm not sure which properies to set.

I removed the call to drawnow in image.m.
