I just searched in the help and this is what it said:
Images can be added to your posts, if the forum administrators have allowed uploading of images you can use this to upload an image from your own computer into your message. However, if image uploading is not available then you will need to link to the image that needs to be stored on a publicly accessible web server, e.g. http://www.mysite.com/my-picture.jpg.
