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/" . $current_user->user_login . "/";
   $path_info["url"] = "http://localhost/mysite/upload-folder/" . $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/admin
( where "admin" is eg. of user login).

But when I add: image -> Set as Featured Image, my files goes to this folder:
http://localhost/mysite/upload-folder

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

Hi Chris,
If You are go to Your site and please right-click on the image (featured image) "show url image".
The address indicated on the photo in this directory (with Your username)?
I'am asking, because I have uploaded image also in directory with username, but this same photo is in other directory and featured image on my website have adress from this second directory.

Sorry form my english :)
