That's not what the alt attribute is for. It is to be presented when the
image is not displayed. It is ALTernative.

And it would be meaningless and disturbing when the image is not seen at
all, which is when the alt text is to be presented. Think about the
presentation of the page in speech, or in Braille, or graphically with
image loading disabled.
The title attribute can be used to provide a *description* or other
advisory title for an image. It is meant to be available (optionally)
when the image *is* displayed.
