http://www.mathworks.com/matlabcentral/fileexchange/46551-cspy-m is other option for this function. In this version is possible plotting more quickly.
Ex:
---------------------------
spyc(rgb2gray(imread('ngc6543a.jpg')));
-----------------------------
cspy(rgb2gray(imread('ngc6543a.jpg')), 'ColorMap', 'hot')
