What will be an ideal response?
Why is alt text important: The text you provide using the alt attribute for an image is an important accessibility element for your Web site. It's also significant from a usability perspective for users who are unable to download the image or who choose to browse without images.
Tips (students should include three tips):
For graphics that include text, the text should be included in the value of the alt attribute, along with a description if it adds useful information.
Photos and other graphics without text should include a description of the image in the alt value.
Because there are many ways to describe any given image, it's important to identify what aspect or aspects of a graphic are relevant to the Web page, and focus on those aspects.
If a graphic is merely presentational and doesn't add information to the Web page, include the alt attribute with nothing between the quotes. This lets screen readers know that the element isn't conveying information and that they can skip it.
