Re: how to detect images having math expressions

I would agree with that but manually visiting every page simply isn't
practical for large websites. I was thinking that a more cost-effective
option might be to assess all the images and identify those that may need
non-null 'alt' attributes. When you find out which pages use these images it
may mean that perhaps only 10% of the pages need to be assessed for that
checkpoint.

Once you get above a few hundred pages it becomes impossible to test every
page for every checkpoint. It is not cost-effective (and may not even be
possible) to do it manually, and automated tools only do a very small part
of the job. I am interested in techniques that make better use of the
available manual resources to do things that automated tools cannot do at
all, when a brute force (i.e. view every page) approach is not an option.
