The term "ALT tag" is a common shorthand term used to refer to the ALT attribute within in the IMG tag. Any time you use an image, be sure to include an ALT tag or ALT text within the IMG tag. Doing so will provide a clear text alternative of the image for screen reader users. ALT tags also provide a keyword association with a specific image, meaning an image is more likely to appear in search engine results for that particular keyword.
