Nice markings! I had trouble figuring out how to get pictures onto my posts too.
To get pictures in your posts, go to tinypic .com and upload a picture. Afterwards, there should be multiple yellow bars with links in them. The IMG Code for Forums & Message Boards is the link that you want, and it will look something like [IMG]http://i59. tinypic. com /et cetera[/IMG ]. Just copy and paste that link into your post, and you'll have your picture. You have to upload each individual picture separately though. I've also heard that you can use deviantArt to get pictures into your posts, but I never use the site.
