2.
3.
Actual Results:  
Nothing happens when you mouse-over the image

alt is for the alternative to the image when you can't see it because images have been disabled. You want the title attribute. It is IE that has the bug, it should not use the alt attribute as the image title.

Actually it "works" only in quirks/IE7 mode. IE8 fixed the bug in IE8 mode.
