Why doesn KHTML show the contents of an images ALT tag in a tooltip?
There’s no standard that says an ALT tag should appear when you hover over an image. Some browsers do so, but that’s all. Most of the time the ALT tag contains some useless description like “foo.jpg (231432 bytes)” as Frontpage does by default; besides, the specification for the ALT property calls for ALT to be displayed in place of the image, as in text-mode-only browsers such as lynx or w3m. It is not meant to be used as a tooltip. Tooltips for images are supposed to come from the TITLE attribute, and this is being implemented.
