Answer 1

Try the following: you can use .filter()and hide the input if the value is empty.

$(function(){
 $('.containerdiv input').filter(function(){
   return $(this).val().trim()=='';
 }).hide();
});

EDIT . Since the OP wants to hide both the input and the image, if the input value is empty, see the updated solution below

$(function(){
     $('.containerdiv input').each(function(){
       if($(this).val().trim()=='')
       {
          //hide parent div and next div having image
          var $parentDiv = $(this).closest('.column-half');
          $parentDiv.next('.column-half').hide();
          $parentDiv.hide();
        }
     });
  });
