My site has been told "The majority (98) of images do not have alternative text specified for users with visual disabilities. The website may be harder or impossible to use for some disabled users, and therefore in violation of legislation in many countries (e.g. UK, US, Australia). 99 images are used as a links, but do not have alternative text. Any images which are used as links should always have meaningful alternative text." I have tried adding alt text to one image. Bottom left of http://realpeterbruce.com under 'Test' Have I got the right idea? Have I fixed that image correctly? Is it worth my time adding alt text to all of the icons above 'Test' ?
