I just made something like that (If I understand you correctly).
I use he function position() include in jQuery 1.3.2.
Just did a copy paste and a quick tweak... But should give you the idea.
// Make images draggable.
$(".item").draggable({
// Find original position of dragged image.
start: function(event, ui) {
// Show start dragged position of image.
var Startpos = $(this).position();
$("div#start").text("START: \nLeft: "+ Startpos.left + "\nTop: " + Startpos.top);
},
// Find position where image is dropped.
stop: function(event, ui) {
// Show dropped position.
var Stoppos = $(this).position();
$("div#stop").text("STOP: \nLeft: "+ Stoppos.left + "\nTop: " + Stoppos.top);
}
});
<div id="container">
<img id="productid_1" src="images/pic1.jpg" class="item" alt="" title="" />
<img id="productid_2" src="images/pic2.jpg" class="item" alt="" title="" />
<img id="productid_3" src="images/pic3.jpg" class="item" alt="" title="" />
</div>
<div id="start">Waiting for dragging the image get started...</div>
<div id="stop">Waiting image getting dropped...</div>
