Going therefore to take a look at it, I notice that the URLs are a bit screwy. In the sample code, the URL is
http://www.yourwebsite.com/somepicture.jpg; but in the explanation, the URL is http://www.your-website.com/image.jpg. IMHO, both URLs should be http://www.example.com/image.jpg, but I don't think it matters much as long as they're the same. By-the-by, how come those URLs aren't linkified? Is it because of the quotation marks?
