Thanks Mark! Back before the holidays Jesse also
suggested using Javascript, on the basis that it would
be better if images were ever used as submit buttons.
It all makes sense and I plan on looking into it soon.
The Javascript is trivial as noted, and anyway I'm
closer to being a Javascript guru than CGI/Perl.

Thanks for this as well, and your spirit of sharing!
