Interesting question and timing there Zoe <smile> (relates to a W3C
thread...)

I am curious about why you are only focused on non-linked images - in my
experience the *worst* user experience is when a non-alt image is a link. In
JAWS/IE it seems to read out the file name of the image, and NVDA/FF it
reads out the full URL, which given some of the dynamically named URLs we
see today can be down-right painful.

As far as JAWS is concerned, yes, I believe you are correct. A few releases
back they changed the default handling of images with no alt, but I don't
recall exactly when that was.

Finally, I wonder aloud if any other screen reader data might emerge from
this group/thread around the same question. I'm thinking of System
Access/System Access To Go, ZoomText, Hal/Supernova, ChromeVox...

Cheers!
