Upload files to multiple folders based on different page

Hi all
is there a way to upload files (just images) to multiple folders based on different pages. the website privacy requires the photos in one page not to viewed by others in another page.

i used the following code to pass the current page path to the ckfinder.html file, from the website header file.

filebrowserImageBrowseUrl : '/blah/ckeditor/ckfinder/ckfinder.html?Type=Images&pagePath=<?=$this->page->getPageAscii($this->uri->segment(3));?>'

what i want is, the website should dynamically create the baseUrl based on page path in config.php
something like this
$baseUrl = '/blah/ckeditor/ckfinder/userfiles/'.$_SESSION['pagePath'];

is there a way to use the startuppage path to achieve the task.

i wish there was a way to get the pagepath variable which has the path information from ckfinder.html to config.php of ckfinder.

or

the $baseUrl variable in ckfinder.html from config.php.

please help me out
Cheers
Calvin
