If you go to " go advanced" you'll find "manage attachments" click there and you can insert pics. You can also copy the url of a pic from the web, then when you are writing your reply click the little icon that looks like a picture of a tree, paste the url. This is how I do it, but there may be a better way. When you're in the "Go advanced" area you can also preview your post to see if it's working out.
