The third episode in the "Introduction to Standards" podcast series has been released! This episode covers a topic that everyone who has ever done work on the Web should be familiar with: Alt text!

Alt text is the "alternative text" for images—basically, if a visitor is using a screen reader, it'll read the alt text whenever it encounters an image. Consequentially, alt text is a way for visitors to "read" the picture if they can't otherwise see it. Most people know alt text as "the yellow box that pops up when you put your mouse over an image."

The new podcast walks you through our Alt Text page and describes how to write alt text for the major types of images listed there: Normal images, decorative images, images of text, image maps, CSS background images, and complex images.
