Use jQuery UI's Dropable

$( 'selector for DIV' ).droppable ( {
    drop: function ( event, ui ) {
        // ui.draggable is a jQuery object representing your image
    }
} );

$('#container').droppable({
   accept: 'img'
  drop: function(event, ui){
    var id=$(ui.draggable).attr('id');
    $.ajax({
      url: 'myurl.php',
      data: {id: id},
      success: function(data){
        //do something with data
      }

    })
  }
});
$('img.draggable').draggable();//assuming all draggable images have a draggable class
