how to save default image to data base?

I have the same image control,fileupload control and a button


i am displaying default image in my image control when form is loaded which is in the images folder in my solution only

i am saving the image into database using fileupload control which the user selected his photograph.

here the situation is some users not interested to give their image,so in this situation i need to save the default image into data base.

now i wrote the below code if the user selected a photo through fileupload control.


string strConnection = ConfigurationManager.AppSettings["sqlcon"].ToString();

        SqlConnection con = new SqlConnection(strConnection);
       

        string Strename = TextBox1.Text;
if(FileUpload1.HasFile)
{
        Stream ImageStream = FileUpload1.PostedFile.InputStream;
        int len = FileUpload1.PostedFile.ContentLength;

        byte[] ImageContent = new byte[len];
        ImageStream.Read(ImageContent, 0, len);


        con.Open();
        SqlCommand cmd = new SqlCommand("sp_InsertPhoto", con);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlParameter Paramname = new SqlParameter("@ename", SqlDbType.VarChar);
        Paramname.Value = Strename;
        cmd.Parameters.Add(Paramname);
        SqlParameter ParamImg = new SqlParameter("@photoclip_IM", SqlDbType.Image);
        ParamImg.Value = ImageContent;//sendingn image param value as imagecontent
        cmd.Parameters.Add(ParamImg);
        cmd.ExecuteNonQuery();
        con.Close();
}
else
{

I want this portion of code when user not selected any file from fileupload control, then i need to save the default image which is already displaying in the image control from images folder.
}

Please help me out.....
