This creates a textarea with a section of HTML code on your website. Clicking inside the block of code automatically highlights it so it can be copied. This is just an example. You'll want to edit the code appropriately.

<p><textarea rows="6" cols="80" onclick="this.select();" style="width: 600px;height: 120px;padding: 10px;"><a href="http://www.example.com/"><img src="http://www.example.com/images/image.jpg" alt="Image ALT Text goes here" title="Image title goes here" width="400" height="300" /></a></p>
<p><small>Additional smaller text could go here <a href="http://www.example.com/">Link text goes here</a> from <a href="http://www.example.com/">Example.com</a>.</small></textarea></p>
