The Yahoo! Accessibility Stakeholders Group decided to do something this week to help reduce the number of unlabeled images on Yahoo! web sites as well as to encourage Yahoo! developers and designers to pay attention to things that are not readily visible on the screen. In other words, you do not always get what you see!

ALT attribute, as it’s known in the developer’s world, is a feature of HTML language to provide alternative text for any image on the screen.

invisible to the user

used by screen readers to describe the image to a blind user or by the browser to display something inside the image placeholder while the image itself is loading (this normally happens on a slow connection)

ALT= campaign

Listen to the screen reader sound sample of images with and without ALT attribute. Can you guess which is which?
