Web form display image

Please can anyone help

I'm trying to display an image in Visual Studio 2010 Web form.
I'm using a Image class.

This is my code and it doesn't display anything

protected void Button10_Click(object sender, EventArgs e)
        {
            
           
            Image1.ID = "Image1";
            Image1.ImageUrl = @"C:\img\Koala.jpg";
}

Please can anyone help. I have to do ot like this because the image control should be dynamic - user should choose an image to display
