No, not by default. But if it's ok, you can make a client side validation using JavaScript. You can use the Dynamicweb.DwSecurity.CaptchaImage class to create the image.

No, coming to think of it, I think you'd be better of using a third party component for this og make your own generator. The class I mentioned is not in use anywhere in Dynamicweb, and thus has not be properly testet. But doing the client side validation requires that you use a PageTemplateExtender to generate the image and to set the value for the javascript validation, but you need to insert that value after the page content has been generated since there are no extenders available for the Weblog module. I wrote an article some months ago describing how to generate tags using this concept which I think would guide you in the right direction: http://developer.dynamicweb.dk/Weblog-16918.aspx?action=ShowArticle&ArticleID=148
