There are two ways to go about it. First, you have to have the pictures hosted on a website somewhere. If you are not able to have someone host them for you, someone on the board may be willing to do so for you. After you have them on the web, there are two buttons at the top of the box when you are posting in advanced mode. The little yellow button will allow you to have the images show up directly in your post. The other option is to use the button next to it. This allows you to put in a link for people to click on, and a new window will pop up allowing them to see the pictures on your site.
Hope this helps, looking forward to seeing the pics.
