(Thus VoiceOver shares JAWS' design flaw that it doesn't check if the file name looks like a readable English word.) It appears that VoiceOver's behavior fits the current spec draft fine except for the case that the image is linked and has no alt. Testing on Mac OS X 10.5.2 with Safari 3.1. Demo document: http://hsivonen.iki.fi/test/moz/alt.html P.S. <img alt="_decorative"> and <img alt="_notsupplied"> would both have bad backwards-compatibility characteristics as far as VoiceOver goes. -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
