Introduction

The alt
attribute is markup defined by the HTML [HTML5] specification that can be placed on
any HTML _img_ image element [and elsewhere? - Liam] to provide a simple textual 
fallback for that case that the image is not displayed.  Appropriate use of
the _alt_ attribute is an important part of creating Web pages that are
fully accessible, not only to people who are blind but also to people in
situations where an image cannot be downloaded or displayed.  The contents of
alt attributes may also be available to Web search engines and to in-page
user agent searches.

This document describes how to use the _alt_ attribute in HTML [HTML5].
