I think Maciej and Steve are both right on track for that example.

The key is to ask yourself what the purpose of what the Webcam is, Ian. To me,
the purpose of the image seems to be to show the weather in Geneva and it does
so from a rooftop angle of view at set times. So a base text alternative like
the following may be worth considering:

alt="A WeatherCam rooftop view of Geneva, Switzerland. Scene updated every ten

However, I wonder if it would  be possible to have the alt updated with date,
time, temp etc with some type of system to match the visual aspect of the
WeatherCam? That would be more helpful. That type of info is inserted into the
image so why cant it be added to the alt automatically? That text might read
along the lines of:

alt="A WeatherCam rooftop view of Geneva, Switzerland. 29 March 2010, 2 AM, 10
degrees Celsius, 50 degrees Fahrenheit, 69 percent humidity. Clear sky."

Think about it a bit. A suitable alt will come to you, Ian. Steve is working on
WebCam  alt examples  too.  Between the two of you I'm sure HTML5 will get some
good samples. Thanks.

The crowdsourcing thing might be good to add further details.
