Ckeditor integration - php

I have problem with the integration of ckfinder into ckeditor…
Both, ckfinder and ckeditor directories are in the same folder ../admin/
The standalone ckfinder work fine but I can’t see the “Browse Server” button in insert image dialog box.

My code is:

<?php
// Include CKEditor class.
include_once '../admin/ckeditor/ckeditor.php';
require_once '../admin/ckfinder/ckfinder.php' ;
// Create class instance.
$CKEditor = new CKEditor();
// Path to CKEditor directory, ideally instead of relative dir, use an absolute path:
// $CKEditor->basePath = '/ckeditor/'
// If not set, CKEditor will try to detect the correct path.
$CKEditor->basePath = "../admin/ckeditor/";
// Just call CKFinder::SetupCKEditor before calling editor(), replace() or replaceAll()
// in CKEditor. The second parameter (optional), is the path for the
// CKFinder installation (default = "/ckfinder/").
CKFinder::SetupCKEditor( $ckeditor, '/ckfinder/' ) ;
// Set global configuration (will be used by all instances of CKEditor).
$CKEditor->config['width'] = 600;
// Replace textarea with id (or name) "editor1".
$CKEditor->replace("tkst");
?>

I think that the problem is in this line:
CKFinder::SetupCKEditor( $ckeditor, '/ckfinder/' ) ;
I have tried every possible combination for the ckfinder path but without any result…
Please somebody help.
Thank You!
