The typical way mot people embed flash is pure ugly. Not only is it ugly, but it breaks the XHTML standard. Luckily, there’s a way around it which is much better than the traditional way, and as an added bonus, has a built in flash plugin check without any javascript!
The data in the object tag (beside the param tag) is only called if the flash plugin is not available. Meaning you can put any html you want there as an alternative. I’m sure if you play around with it you will find how much better this is.
