I'd personally use Kimili Flash Embed for this kind of situations http://kimili.com/plugins/kml_flashembed Basically its very flexible Wordpress plugin for any flash embedding: You activate a plugin, then you can use visual editor to choose settings. It will give you a code like below, which you just put in the page content. [kml_flashembed base=. movie=http://www.x.com/file.swf height=164 width=500 wmode=transparent fvars=abcde=1 /]
