This is very similar to your other thread.
I'll assume that this is about windows forms not WPF.
The following code seems to do the trick.

private void LoadMapImage(string filepath)
        {
            if (!string.IsNullOrEmpty(filepath) &&
                System.IO.File.Exists(filepath))
            {
                if (Map.Image != null)
                    Map.Image.Dispose();
                Map.Image = Bitmap.FromFile(filepath);
            }
        }
