 <p>The primary method for providing text alternatives for images is by including text in the <code>img</code> element <code>alt</code> attribute.  In graphical   browsers the content of the alt attribute is typically displayed along with an indication (bordered area and/or an image icon) of the presence of an image when the image is not displayed, because the user has disabled image display or the image source information is incorrect. Assistive technologies such as screen readers will typically announce the presence of an image followed by the alt attribute content. Text based browsers  may display the alt attribute content  in brackets or in  different colored text or as the content of a link to the image or as text without any indication of the image or  prefixed with an indication of the image.</p>

 <p>The answer to this question very much depends on the context an image is being used in. While there are no definitive right or wrong lengths for text alternatives provided using the <code>img</code> elements <code>alt</code> attribute, the general consensus is that if the text alternative is longer than  75-100 characters (1 to 2 sentences), it should not be considered a short text alternative and should not be presented using the <code>alt</code> attribute.</p>
