Hairyspin can answer your CFS3 question; I only use FS9.
Regarding the posting of pictures, just select Go Advanced, Manage Attachments, next to the Upload files button, select the + sign to add buttons for each picture you wish to upload, then select the files you want, then select Upload files.
Once uploaded, each thumbnail shows with a check mark, if not check each picture to check mark it, then select Done.
You should get what I have in this post with 2 pictures.
Oh, by the way, we were all newbies once. Just keep asking and keep trying until you get there. We are here to help.
