It seems like $avatar_image_new can also be of type false; however, parameter $dst_image of imagecopyresized() does only seem to accept resource, maybe add an additional type check?

The assignment to $result is dead and can be removed.

          imagedestroy($avatar_image);
          $avatar_image = $avatar_image_new;
        }

        if (!imagepng($avatar_image, $avatar_filename, 9)) {
