SqlConnection sqlConnection1 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        SqlCommand cmd = new SqlCommand();
        Object returnValue;

       
        cmd.CommandText = "SELECT COUNT(*) FROM pics WHERE picUrl = 'images2'";
        cmd.CommandType = CommandType.Text;
        cmd.Connection = sqlConnection1;

        sqlConnection1.Open();

        returnValue = cmd.ExecuteReader();

        sqlConnection1.Close();

so it should be

sqlConnection1.Open();

// returnValue = cmd.ExecuteScalar();
// returnValue = cmd.ExecuteReader();
SqlDataReader reader = cmd.ExecuteReader();

if (reader.Read())
{
Label1.Text = reader[0].toString();
}

sqlConnection1.Close();
