Ads not found on http://www.domain.com/images/ Is this serious? How in the hell can I have my links in a folder??? This is crazy. I can't believe people can manage to use this tool. I also can't believe there's no support any longer. What am I doing wrong? Please help..
Do a search for "site:domain.com/images/" on google. If G returns a result for that you need to put a index file with the coop code into that folder or you disallow google to crawl the images folder by robots.txt.
That's not odd behavior. Computers don't behave they obey. If your images folder is returning a 403 status code, then the folder's permissions don't permit access to that directory. Instruct the server (chmod on *nix systems) to permit access to that directory, then create an index file like smaaz has mentioned.
