cked4.php--where I display my ckeditor

session_start();
$_SESSION['IsAuthorized'] = "true"; etc......

config.php--

session_start();
$_SESSION['IsAuthorized'] = "true";
function CheckAuthentication()
{
return isset($_SESSION['IsAuthorized']) && $_SESSION['IsAuthorized'];
}
$baseUrl = 'http://localhost/ckeditor/ckfinder/userfiles/images';
$baseDir = 'http://localhost/ckeditor/ckfinder/userfiles/images';
error---file system permission
now what happens..instead of image it shows red cross sign.i am using windows operating system.php safe mode off.
when i use
$baseUrl = 'c:/wamp/www/ckeditor/ckfinder/userfiles/images';
$baseDir = 'c:/wamp/www/ckeditor/ckfinder/userfiles/images';
the image is uploaded in the specified path but is not shown in the preview nor in the ckeditor.

and yes when give some other path in the url..like:
http://education.oracle.com/education/i ... elcome.JPG
then in this any image is shown in the ckeditor as well preview
