Hi,

the first "bad example" looks like it should be two examples.

Rather than describing a particular image in the examples, distinguish:

a decorative image (one that merely provides rounded corners, a picture of  
people that is additional to rather than a part of the information  
presented, a spacer [if the page fails 3.14] or the like), which should  
have alt="";
an icon, e.g. used as a link to a table of contents which should have  
alt="table of contents", or an icon used to flag a form field as required  
which should have alt="required: " or the like;
an image convying real content such as a data chart, which should have a  
non-visual representation of the data (e.g. tabulated or in lists - but  
note relevant checkpoints here too).

cheers

Chaals
