Try using some Javascript code or jQuery. Please find below jQuery code

Here i have used position() method which gives you left and top position of the element. You can change the selector based on your need.

Update : Assumed you have HTML like <div id='images-container'> .. all images here </div> and updated selector below for that with each() method

You can also use offset()

 <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
 <script language="javascript" type="text/javascript">
    $(document).ready(function () {
         $('#images-container img').each(funcion(){
         var coordinates=$(this).position();
         coordinates.left;// gives you x
         coordinates.top;// gives you y
         //save these values in some hidden field and access it in code behind if needed
       });
    });
 </script>
