Images without a description
Lighthouse / axe call it: Images must have alternate text · Image elements do not have [alt] attributes
A blind visitor's screen reader says "image" and nothing else. If the image is a product, a promo or a button, they simply don't know what it is.
Who it leaves out: blind people (screen readers)🔎 also SEO
How to fix it
Each image needs a one-line description of what it shows. We write them and you approve; your developer pastes them in.
In the code
Add alt="…" describing what the image conveys; use alt="" if it is purely decorative.
