OR modify your function as below:

$(document).ready(function() {      
      $('ul.branch').hide();    
      $('span.ud').toggle(
            function() {
                  $(this).parent().next().show();
                  $(this).html('<img alt="up" border="2">');
            },
            function() {
                  $(this).parent().next().hide();
                  $(this).html('<img alt="down" border="1">');
            }
      );
});
