If you want to post a picture instead of it being an attachement you need to post it from a site like imagestation. That's the one that most people use. You just sign up for an account upload your pics to an album. Then when that is done you right click on the picture that you want to post and select properties from the little pop-up menu and copy the page address. Then all you have to do is click the IMG button on the post section and paste the addy in.
