When people enter /wp-content/uploads/ in the browser they see the content of that folder.
I read this post http://wordpress.org/support/topic/is-there-a-way-to-hide-the-uploads-folder-from-public?replies=6 and this http://wordpress.org/support/topic/hide-directory-structure?replies=4
I uploaded the empty html/php file and a .htaccess, but nothing changes. The content of the folder keeps visible.
What else can I do?
