The more I know about alternative text for images the more I understand the complexity of it. There are differences between users and content creators about decorative and informative image objectives and developers should never decide if image will be decorative or not. HTML standard includes a lot on this as well and should be read by more people for better accessibility and better web in general.
Accessibility for web and mobile seems to be very code-oriented, but it really starts much earlier – in the design phase.We should really shift accessibility left, on the whole picture – from A to Z. That also goes for design and initial product setup, not just developing!
