paginated ability to add photos to articles via habtm association - lacks ability to select photos from multiple galleries

application.js

$(document).ready(function() {

  // ...

  $('.selector_control').live('click', function() {
    $(this).parents('.select_galleries').find('.select_photos').slideToggle();
  });
  $('.all_photos').click(function(){
    $(this).closest('.select_galleries').find("INPUT[type='checkbox']").attr('checked', true);
  });
  $('.no_photos').click(function(){
    $(this).closest('.select_galleries').find("INPUT[type='checkbox']").attr('checked', false);
  });
});
