lolly, you can't post the picture directly from your computer. You have to host it somewhere first. To do so, you can use your website, or blog... if you have one, or you can use a free host. For example
www.imageshack.us You just have to select the picture on your computer, give your email adress, and click on upload. And then, you can use the link imageshack give you to post the picture here. It's the way I do.
EDIT: I just saw the post just before mine. If you want to see the picture, you right click on it, you choose "properties", and then you paste the adress, and it works.
The picture you choose was from "Lord of the flyes", but it's too easy to know, the information is in the adress of the picture (LOTF).
I guess you can choose another one, and post again.
