What I have tried:

                {
                    //if (!(pictureBox1.Image == string.Empty))
                    if (!(pictureBox1.Image == null))
                   
                    {
                    //    this.pictureBox1.Image.Dispose();
                    //    this.pictureBox1.Image = null;
                    }
                    System.Drawing.Imaging.ImageFormat.Jpeg);
                    {
                        SqlConnection con = new SqlConnection();
                        con.ConnectionString = "Data Source=DESKTOP-8BEJFRN\\SQLEXPRESS;Initial Catalog=win;Integrated Security=True";
                        con.Open();
                        SqlCommand cmd = new SqlCommand("SELECT username,pic FROM pe WHERE username='" + textBox1.Text + "' and pic='" + pictureBox1.Image + "'", con);
                        SqlDataReader dr = cmd.ExecuteReader();
