Hello All,
I think over all I would say use null text in agreement with Andrew.
While I think low vision and persons with vision in the past do like to
identify what's there, in an over all sense extra audible detail is not
necessary for the content.

hello Shawn, Andrew and all,
I agree with Andrew's comment below. 
The alt contents are not helpful for someone who cannot see the images
because it cannot help illustrate the visual effect of these images. 
Empty alt tags would be a first solution. But it does not give
equivalent information as the information provided by the images. 
There should be a short text equivalent of each image that should not
explain what the images look like, but this text equivalent should
explain which information they try to provide. 

For the moment, I have no idea of the information that should be
contained in the alt attribute, so I think that empty alt would be
appropriate. 
The process is here provided by the title of each list item and by the
numbering of each item. 
If you take Andrew's example of explaining on the phone the steps
described in hte document, you would not try to describe each image but
you would say : first step is this, second step is that and so on. 

Best
Sylvie
