ALT Tag

The ALT text is meant to provide alternative or substitute text, primarily for use when the image is not being displayed. The most common mistake (apart from not using it at all) is to provide a description of the image, without considering what job the image was doing on the page, leading to results that can range from the incongruous to the absurd. The ALT text should be composed as a suitable textual alternative to the image: sometimes that might turn out to be a description of the image, but in practice that choice seems to be wrong more often than it's right.
