Alternative text

Alternative text gives a route to information or function when an image cannot be perceived visually. Its content depends on why the image appears. An informative image needs the relevant meaning; a functional image needs its action or destination; a purely decorative image may need an empty alternative in the implementation. For a meme, preserve essential visible text and the visual relationship that makes the example understandable. Put long cultural interpretation in adjacent prose rather than forcing everything into a short description. Avoid guessing emotions, identities, or motives that the image does not establish. Test the surrounding reading sequence for unnecessary repetition and missing meaning. The same file can need different alternatives in different contexts because accessibility serves the current reader's task, not an abstract description of every pixel.
