Save Image

I`m trying to save an image besides the user datas to the upload folder and store the filename to the database. Currently the image save is working but the image name is not passed to the database. What do i wrong ?

    $user = User::findOrFail($id);
    $user->fill(Input::except(array('thumbnail')));

    $image = Input::file('thumbnail');
    $path = 'uploads/'.$user->id.'';
    $filename = $image->getClientOriginalName();
    $upload = $image->move($path, $filename);

    $user->save();
