Also, when you are making your post or replying to one, and you want to insert the image, click the 'image' button (it's the seventh one along, the
paint palette in front of the monitor).
When you are prompted to put in the URL of the image, make sure you put in the whole thing.
I've seen a whole lot of pictures similar to that, too bad I can't find them. One of them was a ute under the tyre of one of those huge
trucks used to move tonnes of gravel around.
