Browser-based solutions for website design and construction. You need not know anything about FTP, HTML, Telnet, HTTP, or imaging software. If you can surf the Internet, you can build your own professional looking website. Your web site will automatically be created with all the required images, including logos, buttons, and sidebars. The images can all be generated in the colors you choose, with the desired text. Even professional quality rollover buttons are as simple as selecting a specific layout.
