Thank you!

I disagree with this change. Alternative text should be used when an image is
being used to convey information which would be lost if the image cannot be
seen. Book cover images convey information, but that information cannot be
conveyed in alt text--and we already display the book information as text.

I don't think the alt attribute should ever be used to say something generic
like "image." What use is it to the blind user (for example) to know that there
is an image there? Better to use alt="" in cases where the image adds no useful
information.
