To use Flash elements in your web pages, you must first add the elements to Dreamweaver using the Extension Manager. The Extension Manager is a separate application that lets you install and manage extensions in Macromedia applications. Start the Extension Manager from Dreamweaver by selecting Commands > Manage Extensions.
To find the latest Flash elements for Dreamweaver, use the Macromedia Exchange website at www.macromedia.com/go/dreamweaver_exchange. Once there, you can log in and download Flash elements and other Dreamweaver extensions (many of which are free), join discussion groups, view user ratings and reviews, and install and use the Extension Manager. You must install the Extension Manager before you can install new Flash elements or other Dreamweaver extensions.
For information about using the Extension Manager to install Flash elements (as well as other Dreamweaver extensions), see Adding extensions to Dreamweaver.
