Well, I learned a little more about .htaccess files and moved there the list of banned IP addresses (IP that come from spammers). It should move the load from the site to the server (maybe) resulting in the site being a little bit faster because it has not to check so many IPs. I've updated the .htaccess file in the free stuff page and for the pictures, I don't know if it will work but it should be not possible to see a picture on the site linked in another place...
