As discussed in some post in the past, better yet go to a site like
http://tinypic.com/ and upload your image.

After uploading you will receive a code for message boards which you can copy paste (It's on the left side). The example for the picture above is
- Code: Select all
[img]http://i44.tinypic.com/35byphs.jpg[/img]
Also you can use a picture stored on a site. For instance, while browsing on the web you find this
http://animal.discovery.com/mammals/lion/pictures/lion-picture.jpg.
To repost it here, copy-paste the link here and press the "Img" button

So in this case it would look like this:
- Code: Select all
[img]http://animal.discovery.com/mammals/lion/pictures/lion-picture.jpg[/img]
This is what you get:

To test it out, you can always use the Preview button before submitting your message. You will see the images then
Note: I'm not sure that you can upload images ending in something else than .JPG with the "img" code
