I've read through many of the drag and drop threads on SO and i haven't found one that tells me how to get the child element id of the dragged element, when the dragged element is dropped.

For example if you have

<div id='drag'>
  <img id="something"/>//how do i get this id when #drag is dropped?
</div>

<div id='drop'>
</div>

and the js

$('#drag').draggable({
  containment: '#content',
  scrollSensitivity: 60,
  revert: 'invalid',
  cursor: 'move'
});

$('#drop').droppable({
  accept: '#albumImgs li',
  activeClass: 'dropContainerOpen',
  drop: function(event, ui) {
    var fileName = $(ui.draggable.attr('alt'));
    console.log(fileName);
  }
});
