Videos
It really easy to embed videos from YouTube into your HeadTree. On the YouTube site, when you see a video, just copy the 'Embed' code from the text box on that page, and paste it into the page editor. You will need to use the HTML view of the editor when pasting in your code.
The code will look something like this:
<object width="425" height="350"><param name="movie" value="http://www.youtube.com/1234"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/1234" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object>
Go ahead and look at the 'Family Guy' page to see an example where several videos have been embedded.
