Re: character limit on alt attribute for screen readers

I once did an experiment on this and copied the Declaration of
Independence into an alt attribute many thousands of times. I set the
JAWS speech rate at maximum and let it run for several hours and it
just kept going. So the maximum alt text length is at least a few
thousand pages of text - certainly much longer than anyone would ever
consider.
