Go to http://www.askaninja.com/ and click to play one of the episodes on the "RECENT EPISODES" bar (the ones that say "click to play") and notice how there is a darkening effect to the entire page, with a quicktime object embeded into it that is centered. I want to do the same thing except instead of a quicktime video, I want to embed a flash video.

How do I make the script darken like that and embed a Flash object in the middle? Or just embedding an image file in the middle is fine to (jpg, png, etc).
