I've seen people add images (jpg, png, gif...) images to HTML text and always pondered how they do it. Was never really able to do it though.
Can anyone teach me?
In XHTML, they are required. But, this page doesn't follow any HTML standard, so that's irrelevant. In XHTML you'r also supposed to end your <img> tag with a slash (<img src="http://example.com/image.jpg" alt="Image" />).
Funny, with all these HTML advice in this thread, none of the URIs shown are proper links ;)
