Before we get into anything else let’s first go over what HTML is. HTML
stands for Hyper Text Markup Language. This is the basic format for the
scripting language that is used to construct the Web. The latest version
of HTML (HTML 4.01) was developed by WHATWG (Web Hypertext Application
Technology Working Group). They are now working on a revised version
called HTML5 which focuses on the needs of application developers along
with resolving issues found in the previous versions of HTML. Here is an
example of what the current HTML code would look like if you were
adding an image.
<img src="image_name.jpg" width="251" height="143" />
