I use the album in my profile to post pictures. Across the top of the page you will see a tab that says USER/CP. Click that and then find the pictures/albums tab along the left side of the page. Once you go there you can upload halloween related pictures into your album. When you want to post a picture, go to that picture and open it, there will be 2 lines across the bottom. One cantaines a BB#, copy and paste that into the thread.
