While not exactly a banner exchange script, AutoPub allows one visitor at a time to add his/her link with a little banner on your page which will remain until the next visitor replaces it with his/her submission. Configurable parameters include: delay time, color, fonts, banners width and height. Also features: a gallery page to show all the old banners, a complete automatic installation and a password protected admin panel.
2.1a: added a little anti-hackers protection.
