Re: Thoughts on professional portrait (headshot) images?

To answer the question of whether headshot images should have an alt text,
go back to first principles. First ask the question, "Does this image give
any information to sighted people?"

The answer is yes, of course it does - headshot images give all kinds of
useful information to sighted people. (Whether everyone wants that
information is not relevant - some sighted users will be interested in the
information.) Therefore you must give it an alt text for blind people, as
required by WCAG 1.1.1.

To do otherwise is to deny blind people the right to even know that an
image of the person is present. The fact that it is difficult to decide
what information should be given in the alt text is not a reason for not
giving anything at all!
