I've found stuff on the web that works in I.E, but nothing that should work in most browsers.

Any donations welcome :)

I don't think it's possible. Well, I've never seen any scripts that will do it in anything other than IE.

IMO these type of scripts aren't really that helpful unless they are fully cross-browser compatible, and even then they can sometimes feel like they are there just there "because I can", if you know what I mean.

I'd just resort to instructions on how to do it manually for those that don't already know.
