I ve included it here because you ll probably see it on other sites but there are better ways to embed media into a web page. Embedding Flash Movies Using SWFObject SWFObject is a combination of markup and JavaScript that provides a way to embed Flash movies in web pages using standards-compliant markup that still supports all the browsers that are currently in use. JavaScript is a programming language that runs within the context of a web page. I explain how it works in more detail in Lesson 14 Introducing JavaScript. You don t need to know how to program in JavaScript to use SWFObject you just need to copy and paste some code and fill in a few blanks. To download SWFObject and read the documentation go to http p swfobject . Aside from providing a reliable way to present Flash movies using standards-compliant markup SWFObject also works around a problem that can t be dealt with using markup alone. When the version of the Flash player a user has installed is too old to play a movie the movie will not be presented and any alternative content you provided will not be displayed. The browser hands off the movie to the Flash player assuming it will work and doesn t handle things gracefully if it does not. SWFObject uses JavaScript to catch these errors and show the correct alternative content when they occur. SWFObject provides two approaches to embedding content one uses markup augmented by a bit of JavaScript the other uses pure JavaScript. Using markup provides better performance and offers some level of functionality if JavaScript is disabled or the content is republished in an environment where the JavaScript is not included. The dynamic version is a bit more flexible in that it enables you to configure the embedded player on-the-fly. Using SWFObject with markup referred to as static publishing requires three steps adding the object tags
