I employ the "cgi_img_auth.php" method of securing the images directory.  I 
believe the "image_auth.php" method is similar.  With this method a .htaccess 
is placed in the /images directory containing "Deny from All".  Another 
.htaccess in the wiki's main directory contains a rewrite rule that takes any 
requests for access to the images directory and re-routes it through the 
cgi_img_auth.php code, which verifies authentication before allowing access to 
the images directory.  This prevents unauthenticated users from directly 
accessing the images files, for example with a direct url to the image file.  

Its not clear to me that with this in place I need to also add the rewrite rule 
in the images directory, but if this is still needed, where would I place it?

Yes, the same issue existed in 1.17 and trunk before the release date.
