Dreamweaver was designed to be extensible. As a result, you can expand Dreamweaver’s capabilities through the use of extensions—pieces of software that can be added to increase the functionality of the program. There are several different kinds of extensions, ranging from simple HTML objects to more complex JavaScript commands. The Dreamweaver Extension Manager is used to install, manage, and remove extensions.
You can create new behaviors and extensions for use in Dreamweaver yourself or you can obtain extensions created by others from the Dreamweaver Exchange Web site. There are a wide range of extensions available on Macromedia’s Dreamweaver Exchange, ranging from ones that you can buy to freeware-style scripts. In this lesson, you will use extensions that have been provided for you on the CD that accompanies this book.
