The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free?
Alan Kay, in the interview with Dr Dobb's Journal (2012)
img title vs image alt
Alt text is meant to be an alternative information source for those people who have chosen to disable images in their browsers and those user agents that are simply unable to “see” the images. Google officially confirmed it mainly focuses on alt text when trying to understand what an image is about.
Image title should provide additional information and follow the rules of a regular title: it should be relevant, short, catchy, and concise (A title “offers advisory information about the element for which it is set.“).
