Sure - I agree.  I was assuming what Guillaume was getting at was
wanting to say that an image on a page that is there as a green light
to say, for example, an order has been accepted, which should also
have a machine readable alternative, so therefore it seems acceptable
to me to use the @alt with the content of "Order accepted", perhaps.
That would make sense read out still.
