I've had a stubborn image too, that wouldn't go away by setting the Image and InitialImage to null. To remove the image from the pictureBox for good, I had to use the code below, by calling Application.DoEvents() repeatedly:

            Application.DoEvents();
            if (_pictureBox.Image != null)
                _pictureBox.Image.Dispose();
            _pictureBox.Image = null;
            Application.DoEvents();
            if (_pictureBox.InitialImage != null)
                _pictureBox.InitialImage.Dispose();
            _pictureBox.InitialImage = null;
            _pictureBox.Update();
            Application.DoEvents();
            _pictureBox.Refresh();
