Tutorialzine have created a Free Ajax Web Chat script which you can use on your website. The best feature is that it fetches the profile picture from Gravatar websites. In this web 2.0 world where most of the users have a gravatar picture, this chat can be very useful for wordpress blogs and websites to give the incoming user a platform to interact. It is one of the best open source web chat script i have come across and that too in php and mysql.
