There are plenty of reasons that "good enough" alt text may not be available, but no one has come up with an example where *nothing* was known about the image. You just posted your four main examples, and there was indeed information. Not as much as we would like, but quite a bit more than nothing. You then said that information wasn't suitable for alt text, because it should be in a visible element instead -- which it could be, if aria-describedby were used to link the two elements. -jJ
