glDrawPixels(256 /*Width*/, 256 /*Height*/, GL_LUMINANCE /*Image format*/, GL_SHORT /*Data type*/, buffer /*Image pointer*/);
Hope that helps.

Now that I think about it, you might have to make buffer a pointer first by adding an '&' before buffer... I'm not sure (I don't use glDrawPixels a whole lot).

Just out of curiosity:
Why are you wasting 16 bits per pixel on a monochrome black and white image?
