Scrolling Horitionally whil fitting photo's vertical edge to picturebox and panel respectively

Hi all,

I'd like to display a very long panorama in a c# form. The panorama is placed in a picturebox and the picturebox is placed inside a panel. I am not sure if there's way to fit picturebox's vertical edge (and at the same time picture's height are resize to fit the height of picturebox) to the panel (that means vertical scrollbar is not needed) while allows users to scroll horizontally.
