That rather depends on what you mean by "descriptive information". The alt
attribute should carry the *text alternative* for the *meaning* of the
image. So "available" might be correct, but "green ball" is not. Neither
A useful rule of thumb is to read the page out loud, as though you are
doing so to someone, via a telephone. What would you say, when you came to
such an image?
