This formulation is often used to mark up different types of items such
as new or discontinued and often, the images are differently colored
swatches, circles, butterflies whatever and the attention drawer is to
insure that if this is indeed the case, the image should not be the only
way in the link that the information about the property of the item is
conveyed that is conveyed by it.

I'd like to make a further comment on the code sample though.  the
second alt tag is meaningful.  The first is not.   I have not looked at
the others.

Subject: Bobby inaccuracy?


I've just run a AAA Bobby test on a page and although it passed it
included
the usual user checks on colour and images conveying information.
However it
flagged all lines with <img> in the section about using colour to convey
information as well as that about using images.

If you use color to convey information, make sure the information is
also
represented another way.

If an image conveys important information beyond what is in its
alternative
text, provide an extended description.

I've looked at the relevant guidelines (WAI checkpint 2.1) and can see
no
reason for this.

Can anyone enlighten me?
