Pass the URL of the selected file in KCFinder to CKeditor 3

I have create a simple CKEditor installation using the PHP method as below..

require_once('../includes/ckeditor/ckeditor.php');
$ckeditor = new CKEditor();
$ckeditor->basePath = '/includes/ckeditor/';
$ckeditor->config['width'] = '850';
$ckeditor->config['height'] = '300';                        
$ckeditor->editor('text_content', stripslashes($HTMLMessage));

I've added kcfinder using the following code within the ckeditor/config.js file

config.filebrowserBrowseUrl = '/kcfinder/browse.php?type=files';
config.filebrowserImageBrowseUrl = '/kcfinder/browse.php?type=images';
config.filebrowserFlashBrowseUrl = '/kcfinder/browse.php?type=flash';
config.filebrowserUploadUrl = '/kcfinder/upload.php?type=files';
config.filebrowserImageUploadUrl = '/kcfinder/upload.php?type=images';
config.filebrowserFlashUploadUrl = '/kcfinder/upload.php?type=flash';

The KCFinder installation is working now - I just cannot pass the correct URL of the selected file - as the script will generate dynamic folders as follows - so user1 can only access their images and not user2 images and vice-versa.

user1/images
user2/images

I have found this link which explains the interaction between CKEditor & the File Browser - which method should I use (I'm not 100% clued up on CKEditor so be easy on me please - Can someone explain which kcfinder/ckeditor files I need to edit in relation to the URL below

Thanks in advance
