RewriteCond %{HTTP_REFERER} !^$
ReWriteRule .*.(png|gif|jpg)$ - [N,F,L]

Answer 1

I think you're missing an escape for the . in your domain name:

Options +FollowSymlinks
Options +SymlinksIfOwnerMatch

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(.+\.)?article-stack\.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
ReWriteRule .*.(png|gif|jpg)$ - [N,F,L]

Answer 2

I tried your code on my local setup and it worked fine. It's likely that something else in your .htaccess is causing this to fail.

I notice that you are rewriting the images to http://article-stack.com/- which redirects to another page. It would be best to rewrite to another image or to a 404 error.
