The positive alt-itude! An inclusion tool for your accessibility
summary
Gives practical rules for writing image alt text: always include an alt attribute, use an empty alt (alt="") for decorative images, and avoid vague labels like “image” that confuse screen readers. Recommends putting large data or charts in a nearby caption rather than the alt, providing exhaustive descriptions for artwork, and giving icons/buttons a single clear label; notes auto-generated alt text from social platforms and AI (e.g., MidJourney) often lacks context and references RGAA accessibility norms.
