I'm adding to my FAQ and in one of my 'post' I have to put a image like this one

I tried putting [img][/img] and just the url but I haven't been able to. So if someone could help me, I'd really appreciate it.

Also I tried writing a list but when I save it and check it in the FAQ area its not in a list but like a sentence. How can I make my list stay after I save?
