Here's an example of an embedded GigaPan panorama, without snapshots:



I just typed this in the Compose tab (you could also edit it in the Edit Html tab too):

<embed type="application/x-shockwave-flash" src="http://gigapan.org/viewer/PanoramaViewer.swf?url=http://share.gigapan.org/gigapans0/156/tiles/&suffix=.jpg&startHideControls=0&width=44980&height=10125&nlevels=9&cleft=0&ctop=0&cright=44980.0&cbottom=10125.0" height="300" width="100%"></embed>

If you know the ID# of your gigapan (it's on the right side of the URL when you're viewing your gigapan), enter it at this page: http://geocoder.us/gigapan/embed.html

Then, look at the "embed" code it produces (scroll down below the panorama to see it).
