I think what you are looking for is something like this (this is barebones, and would need a lot more error checking, etc.). Make a button to save the image (or however you are going to handle that aspect of it).

    private void SaveMe_Click(object sender, EventArgs e)
    {
        SaveFileDialog save = new SaveFileDialog();
        save.Filter = "JPEG files (*.jpg)|*.jpg";//change for your needs
        if (save.ShowDialog() == DialogResult.OK)
        {
            pictureBox1.Image.Save(save.FileName);
        }
    }
