The #onDrop: event of SUDroppable that passes you all the information you need:
the event object, the dragged element and the container element.

Try something along the following untested code ...

html droppable
    onDrop: (html request
        callback: [ :p | p inspect ]
        value: (html element
            alias: 'arguments';
            property: 1;
            access: 'offsetTop')

... and you should get an inspector within the image giving you some
data about the dropped position.

Hope this helps,
