I have never had the need to create masses of thumbs, but by googling "create thumbnails" (WITH QUOTES), I came up with at least 7 viable, different ways of doing what you are trying to do. Anything from Frontpage, to other 3rd party plugins & programs, plus there looks like ways to do it with PHP also by the look of things.
