Many technical WWW sites uses the same graphics i.e. for ActiveX Controls or the button for "Netscape now" a you have to download it every time. But there might be the problem, that everyone has to use the new tag. By now not everyone uses tags like alt in formatting images and so its hard to imagine that all the webauthors will use this new tag. Volker
