Answer / chaitu
The longdesc attribute of the img element has been around since HTML 4 and is also valid in HTML5. This attribute is designed to provide a more detailed description of an image, compared to the information offered in the alt attribute. The interesting thing is that instead of providing a description by itself (like the alt attribute does), longdesc points to a hyperlink containing the description.
An example of the use of longdesc is presented below:
<img src="italy.jpg"
alt="This image represents the map of Italy" longdesc="italy.html#description">
<!-- other content here ... -->
<section id="description">
<h2>Italy</h2>
<p>The shown map of Italy illustrates its division
in regions...</p>
</section>
