But wouldn't a sensible strategy be: 1) If TITLE="", no tooltip; 2) If TITLE is anything else, use that as the tooltip 3) If no TITLE, but ALT, use the ALT as a tooltip 4) If neither TITLE nor ALT, use "[IMAGE]" as a tooltip (since IMGs without ALT are wrong anyway) That way, authors would provide ALT and then override it with TITLE if it made a bad tooltip. Sometimes a sensible ALT also functions fine as a TITLE. For instance, some images carry essentially non-textual information, and the only reasonable ALT is something like ALT="[Photo of the White House]". Also setting TITLE="Photo of the White House" seems redundant. Also, I'm not sure how one would get around the problem of viewing ALT text for IMGs whose WIDTH and HEIGHT make them too small for the ALT to fit, or for that matter for images that are already loaded. Perhaps that information could appear in a right-click menu. (Since people who want to see the ALT text when the images are already loaded are probably rare.) John T.
