the browser was never *supposed* to show alt attributes as 
tooltips... MSIE did that as a *feature* (which NN and others 
adopted, unfortunately), which had the unfortunate impact of 
making developers rely on alt attributes for extra content, as 
opposed to entering information useful to users with images turned 
off (or those who can't see them)...  i once went to a site where the 
nav buttons were wonky metaphors, but the alt attribute actually 
told you what the button was in plain english... one of the few sites 
out there unintentionally more suited to the blind...

one way you can override it in IE4+ for windows is to add a blank 
title attribute, since it will give preference to the title attribute over 
the alt attribute... however, this will not affect NN4- or most other 
browsers that incorrectly display alt attributes...

nope, that's completely up to the browser to determine... by 
default, it generally uses the OS's default method of displaying tool-
tip-type content...
