Overview: Describe to search engines what your images represent

If your webpages use images, image maps or photos, you should make use of the ALT image tag. ALT image tags are an extension to images which displays alternative text for users who cannot read images (such as Search Engines). This is most beneficial with search engines that index full text, because you are now providing search engines a textual representation of your graphics and the ability to index more content about your website. The more images, the more advantage you have in using the ALT image tag, giving you room for more descriptions to include in search engines. This technique has shown to be quite effective, especially for users who have graphics at the top of their pages and with users who use a large number of images. The syntax for the ALT image tag is included below including a sample usage.
