Change Gtk.Button image from embedded resource

I've been trying to set a button's image from code in a GTK (Mono) application i'm building in Xamarin studio, but so far i've had no luck. I can't seem to get any of the methods that work for C#.Net to work in Mono.Netm and I have no idea where else to turn since I've searched the web for anything I could think of, and the only results I got were for C#.Net.

My question is simple, and I hope I've overlooked something and that the answer will be simple too:
What would be the way to set a Gtk.Button image from an embedded resource by code?

Things I've tried:
* Reflection
* ResourceManager
* Image.FromStream (Doesn't exist in Gtk.Image)
* Whatever I could think of...

Chances are I did something wrong along the line but if so I have no idea what, so please help me out, even if it's by pointing me in the right direction on google...

EDIT:

For some reason @Jester's solution didn't seem to work for me because if you change a button's image, and right after change it's label, the button will only display the label and remove the image. But that's a poblem for another thead.

Not sure how you managed to miss the Image.LoadFromResource method or the associated constructor :)

That is you can simply do:

btn.Image = Image.LoadFromResource("name-of-resource");

Update: works fine for me with this sample code:

using Gtk;
using System;

public class ButtonApp  
{
        public static int Main (string[] args)
        {
                Application.Init ();
                Window win = new Window ("Button Tester");
                win.SetDefaultSize (200, 150);
                win.DeleteEvent += new DeleteEventHandler (Window_Delete);
                Button btn = new Button ("Click Me");
                btn.Image = Image.LoadFromResource("pic");
                win.Add (btn);
                win.ShowAll ();
                Application.Run ();
                return 0;
        }
        static void Window_Delete (object obj, DeleteEventArgs args)
        {
                Application.Quit ();
                args.RetVal = true;
        }
}

Compile using: mcs -res:foo.png,pic -pkg:gtk-sharp-2.0 ButtonApp.cs
