javascript offset value for a image
I am trying to capture a click event on a image (which is a background-image of a div). I have the following code:
findPos:function(obj) {
var pos = new Object();
pos.x = pos.y = 0;
if (obj.offsetParent)
{
do
{
pos.x += obj.offsetLeft;
pos.y += obj.offsetTop;
} while (obj = obj.offsetParent);
}
return pos;
}

Are you looking for something like this:
http://jsbin.com/ogarof/
$("#special").click(function(e){
var x = e.pageX - this.offsetLeft;
var y = e.pageY - this.offsetTop;
$('#status2').html(x +', '+ y);
});
<html>
<head>
<script class="jsbin"
src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
</head>
<body>
<h2 id="status2">
0, 0
</h2>
<div style="width: 100px; height: 100px; background:#ccc;" id="special">
Click me anywhere!
</div>
</body>
</html>
Simply find the coordinates of the div, just as you are doing, and subtract them from the mouse coordinates of the click event.
