Flash can be make Web sites look pretty but for one reason or another not everyone has the player installed on the client browser. If you or your users are one of those poor unfortunates that has a 64-bit linux distro or you just hate having animations on your Web page, then you are forced to go without flash.
In this article we'll show you how to build a more usable carousel in JavaScript instead of Flash.
