There is more than words to writing ALT text

Sarah Horton was a pioneer when, working at Yale University Medical Center, she co-penned the Web Style Guide. This guide to producing Web content was aimed at Yale employees, but was quickly grabbed up by Websters everywhere trying to figure out this new medium.

Now, Sarah has done the same service for accessibility in her book Access by Design: A Guide to Universal Usability for Web Designers.

She is also a blogger at InformIT's Web Design Guide blog. In this week's post, she talks about how and how not to use ALT text with images to improve accessibility.
