string strSQL = "SELECT images.location, products.description, products.price, products.isNew ";
strSQL += "FROM images INNER JOIN products ON images.idImages = products.idImage ";
strSQL += "WHERE products.idCategory=" + str_idButtons;
strSQL += " AND products.doShow=1 ORDER BY products.isNew DESC"; //new first

MySqlCommand command = new MySqlCommand(strSQL, con);
con.Open();
