Upload path doesnt work for featured image

Hello,
I added this code to the functions.php:
==============================================================

add_filter("gform_upload_path", "change_upload_path", 10, 2);
function change_upload_path($path_info, $form_id){
global $current_user;
get_currentuserinfo();

$path_info["path"] = "C:/xampp/htdocs/mysite/upload-folder/test/" . $current_user->user_login . "/";
$path_info["url"] = "http://localhost/mysite/upload-folder/test/" . $current_user->user_login . "/";
return $path_info;
}

==============================================================

when I add: custom filed -> Field Type: “file upload” and Custom Field Name: “existing” – everything works fine: files go to this folder:
http://localhost/mysite/upload-folder/test/admin
( where “admin” is eg. of user login).

But when I add: image -> Set as Featured Image, my files goes to this folder:
1) http://localhost/mysite/upload-folder (so, this is path define in wordpress “general optin”->”media”, not from my function)

and here:
2) http://localhost/mysite/upload-folder/test/admin

(So, there is 2 copy of this one image.)

But image set as “featured image” unfortunetly come from first path.

I want to send files to the same folder as in the previous case.
Any ideas?
I will be grateful for the quick response.
