[jQuery] Newbie -- How to retrieve img src value in function?

[dennis]

I am using jquery 1.1.2, interface 1.2, working with drag/drop.
When user drops an image onto the drop area, I want to retrieve the
src value, so that eventually I can send that value to the server
and do some Ajax stuff. But so far, in my code below,
I have only gotten this to work:

  var thePhoto = drag.innerHTML;

That returns <img src="static/galleries/JQm49CWi09/_t/
lilly01_fuy.jpg">

 How can I just get the src string?


// The code
<script type="text/javascript">
$(document).ready(
function() {
 $('#drag').Draggable( );
 $('#dropbox').Droppable(
  {
   accept :     'dropaccept',
   activeclass: 'dropactive',
   hoverclass:  'drophover',
   ondrop:      function (drag) {
       var thePhoto = drag."what should go here?";
       //var thePhoto = drag.innerHTML; // almost there
        alert( thePhoto );
        },
   tolerance:   'fit'
  }
  );
}
);
</script>
