Drupal 7.50, nel resoconto sullo stato, mi dà messaggio di errore:

Public files directory Not fully protected See http://drupal.org/SA-CORE-2013-003 for information about the recommended .htaccess file which should be added to the sites/default/files directory to help protect against arbitrary code execution.

Ho provato ad inserire, nel .htaccess, la stringa:

# Turn off all options we don't need.
Options None
Options +FollowSymLinks

# Set the catch-all handler to prevent scripts from being executed.
SetHandler Drupal_Security_Do_Not_Remove_See_SA_2006_006
<Files *>
  # Override the handler again if we're run later in the evaluation list.
  SetHandler Drupal_Security_Do_Not_Remove_See_SA_2013_003

# If we know how to do it safely, disable the PHP engine entirely.
<IfModule mod_php5.c>
  php_flag engine off

... però, così facendo, pur risolvendomi il messaggio di errore, il mio sito drupal non visualizza più le immagini!
Come devo fare??
