Flash is an animated image format from Macromedia (now part of Adobe) that is widely used on the Web.
To embed Flash:
Begin the object element with <object.
Use type="application/x-shockwave-flash" to indicate the MIME type for Flash animations.
Type data="filename.swf", where filename.swf is the name and location of the Flash animation on your server.
Specify the dimensions of your animation with width="w" height="h", where w and h are both values in pixels.
Finish the opening object tag by typing >.
Add <param name="movie" value="filename.swf" />, where filename.swf matches what you used in step 3.
Type </object> to complete the object.
This technique is based on the article Flash Satay by Drew McLellan in A List Apart (www.alistapart.com/articles/flashsatay).
Drew figured out a way to use small reference movies to help Flash animations stream properly with this technique. See his article for details.
Many people use a combination of object and the non-standard embed tag to insert Flash on a Web page. For more details, search for embed Flash on Adobe's site (http://www.adobe.com/).
