In the case of  http://www.hb9bza.net/netcam/ the image contains text (blue
strip at top of image) information that is not provided elsewhere on the page,
so the alt should at least include that text. same goes for example 2
http://www.goldengatebridge.org/

on the initial page of http://observatories.hodar.com/webcams.html all of the
webcam images are the sole content of links, so the image alt should be
describe the link target. same goes if you follow a link (e.g.
http://observatories.hodar.com/sunspot/webcams.html) the images on this pages
are also links and also contain date text so the text should be in the alt
text.

do you have any further web cam examples that you would like text alternative
advice on?
