How can I manually select and zoom a part of image displayed on Axes?

I am displaying a grayscale image on axes component, what I would like to do is select a rectangular part of the image using the mouse and then zoom this (enlarge to the size of original image) and display on the same axes.

See imscrollpanel(). I have a demo on my other computer. I'll try to remember to attach here it once I sync up my two computers.
