What is the difference between Preview and Publish?
Preview generates HTML that references your assets where they exist on your computer. All links are created with absolute, local paths prefaced with the file:/// link prefix. In Preview, because of this local pathing, components are disabled. (Version 4.0 browsers prohibit most Java applets from running under local conditions.) Preview automatically creates a directory named Preview in the sites directory. The Preview directory contains all the HTML that is generated for the site, as well as a directory containing those images that NetObjects Fusion must generate, such as banners and navbar buttons.
