A "img" element is an inline element that you can use to define an inline image to be included in a XHTML document. Here are basic rules about an "img" element:

  • "img" elements are inline elements.
  • A "img" element must have empty content.
  • A "img" element requires an attribute called "src" to specify the URL of the image file.
  • A "img" element requires an attribute called "alt" to specify the name of the image.
  • A "img" element will cause browsers to fetch the image, and displayed it inline in a paragraph block. The image name will be displayed when users mouse over the image.

Here is a simple example of an "img" element:

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  <title>Inline Images</title>
  <h4>Inline Images</h4>
  <p style="background-color: #eeeeee; padding: 8px;">
   What's the image title? 
   <img src="/moonrise.jpg"" alt="Moonrise"/>
   Mouse over the image to find out.</p>

If you save the above document as inline_image.html, download this image file and view it with Internet Explorer, you will see an image embedded inline in a text paragraph as shown below:
