all you have to do is click the reply button. At the top there is a IMG tab you can click...click that 1st then paste the url of the pic right after what it going to pop up on the screen after you clicked it.....then after you paste the URL click the IMG again and your done. The picture has to be hosted some where on the internet before you can do this...you can't do it of you computer drive....pretty easy I just learned how to do it a littlewhile ago
