Rails spinoffs - Sep 2005 - altering revert effect based on if dropped on given droppable?

Hi All

Does any one know how to specify a different  reverteffect on a
draggable if its successfully dropped on a given droppable?
What I need to do is when an image is dragged onto a droppable image I
want the drop image to be replaced with the drag image, the drag image
to fade out and then reappear where it was at the start of the drag, as
opposed to the draggable scrolling across the page back to where it was
origionally if it wasn''t dropped in the correct place

this is my droppable code:

   Droppables.add(''page1'', {
     accept: ''image'',
     hoverclass: ''drophover'',
          onDrop: function(element, lastActive) {

              $(''current_image1'').src = element.src ;
 
             element.options.reverteffect =  new
Effect.FadeAndRevert(element);
      
       }
      

}
 );

I''ve hacked together this into  effects.js

Effect.FadeAndRevert = function(element) {
  options = Object.extend({
  from: 1.0,
  to:   0.0,
  afterFinish: function(effect)
    {

      alert(element.style.left);//ok this works
      element.style.width = "330px"; // and this
     
    oEl     = $(element);
    oEl.style.left = ''500px'' //and this
      effect.setOpacity(1);
      }
  }, arguments[1] || {});
  return new Effect.Opacity(element,options);
}

maybe my brain is too tired but I can''t see how in the FadeAndRevert
function I can get the drag images origional location before it was dragged?

Any thoughts on a postcard please
