[Gtk-sharp-list] Changing image

[Boyan Dzambazov]

Hi All,
I'm new to GTK# and I have some problems :)
I'm trying to create ScrolledWindow add image to it and later change this 
image:
ScrolledWindow ImgWin = new ScrolledWindow(); 
ImgWin.SetPolicy(PolicyType.Automatic, PolicyType.Automatic);
Gtk.Image img = new Gtk.Image("./images/out.jpg"); 
ImgWin.AddWithViewport(img);

This is working but I can't find a way to replace this image with the new 
one: ./images/out1.jpg

Can anyone help?
