Also, when i try to move the file to other directory i have this error: "Call to a member function GetUploadedFile() on a non-object in /var/www/vhosts/weberos.es/copiaWeberos/tinymce/jscripts/tiny_mce/plugins/linkdesc/dialog.php on line 159"

this is the line: $mvcfile=$uploader->GetUploadedFile($_POST["myuploader"]);  

 I have seen that $_POST["myuploader"] have a GUID.
