saving ms publisher files in a different file format

[Nancy]

I create a business card in microsoft publisher 2000. I
save it. It saves as a .pub file. If I want to use the
file in email or paint shop or whatever, none of my
programs will accept .pub files. And, publisher won't let
me save the file as a .jpg, .gif, or anything like that.

How do I save or convert or ? a publisher file in another
file format so I can insert it into email, word, paint
shop, or any software program I need to use it in?

Appreciate any help,
Nancy
