You can tell imshow() what values to map to zero and what to map to 255 via the input arguments.

imshow(grayImage, [40, 200]); % 40 will be black (0) and 200 will be white (255)

Plus you can stitch together images like

wideImage = [image1, image2];

which is essentially what showpair() does. Then you can use imshow() like above.
