Integrating CKfinder with CKeditor

I purchased CKfinder but I am unable to integrate to CKEditor. Here is the structure of my application
----application folder
---------ckeditor
---------ckfinder
---------editor.php

I am using jQuery and according to the documentation that I saw online, this what I did :

<script type="text/javascript" src="Js/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="ckeditor/adapters/jquery.js"></script>

<script type="text/javascript">
   
      $(document).ready(function () {

           $('#editor1').ckeditor();   
           var editor = CKEDITOR.replace( 'editor1' );
           CKFinder.setupCKEditor(editor, '/ckfinder/' );   

      });     
   
</script>

The editor is appearing very well but when I click on the Image icon, the window does not still appear with Upload icon

Thanks
