If you click on "Go Advanced" right under the reply box, you will have an additional feature to add attachments, that is what I did when I uploaded the pics in my test drive post and in that box you have a choice to upload from your hard drive or from a website.....I think the insert picture image only allows pics from a url though. The pictures I uploaded were attachments so they come in as thumbnails, and it looks like there is a limit of 5 at a time
