Yes, I think that part's clear. Seems to me, though, that there's an extra complication that hasn't been discussed. Consider an image used as an anchor link, as they often are. Then we in fact have three items (and their purposes are more or less as I give them here, I believe): 1. The IMG ALT - provides alternative text for the image 2. The IMG TITLE - provides supplementary information about the image itself, 3. The Anchor TITLE - provides supplementary information about the target of the anchor link. My question would be, how should these items be displayed or otherwise made available? There's general agreement that the ALT text must be displayed _instead_ of the IMG, when the IMG isn't viewed. MSIE uses item 2 as a tooltip. However, Opera (at least some versions) uses item 3 as the tooltip. I can see logic in both approaches. Should all three be somehow available, and if so, how? best regards
