Re: Investigating the proposed alt attribute recommendations in HTML 5

Hi Maciej

 Because of the different support provided by AT the safest bet would be, if
the image is the sole content of a link,  a description of the links target
page, not a description of the image. for example:

<img alt="Sgt.Pepper and Robinone Individual Photo Page">

This way if the image/link combination is accessed out of the context  of
the implicitly associated title text (e.g. if the user tabs through the
links or uses the G key - in JAWS to navigate through images or uses the
JAWS link list functionality) the user will be provided with useful
information about the link target.

I think the main point is, that the omission of the alt attribute in any of
the examples provided is not the answer.
