WWP server: Something new

Hi,
now that we've begun "Beginnings", i'd like to talk a bit about a new feature on the server: how you can define the panorama thumbnail image yourself.
Sorry, no, it's still not 100% interactive/instantaneous, but this new option should help us to avoid thumbnails with obviously bad image cropping (of head/feet/buildings etc).
Here's how to:
1) upload your panorama as usual
2) beneath the three upload buttons "normal", "fullscreen" and "soundtrack", you'll notice a new text line, saying "Thumbnail view is ...", with the "[EDIT]" box.
3) This leads to a text link (sorry! lazy recycled coding...), and another click takes you to a pop-up window where your panorama will load into a 200x100 view, the same size as the thumbnail. This should give a pretty accurate display of the final result, except for a certain "pixelated" look that Quicktime always gets when scaled down to such small sizes.
4) Rotate/zoom until you're happy with the view.
5) press the "Set thumbnail view" button.
This needs Javascript, interacting with Quicktime and reading the pan/tilt/zoom angle every 0.3 seconds. I've successfully tried it with Mac/PC and my "known" browsers (IE 5-7, Safari 3 + 3.1, Firefox 1.5 and 2), on XP, Win2000 and MacOS X 10.4/10.5.
If you don't want to try this feature, just leave it at the default (0/0/0) setting, which means that (as before) the standard view you used to build the panorama will become the thumbnail (including any vertical cropping that may occur).
For a short step-by-step video, take a look at:

The thumbnails are built later by downloading a list of those angles, and parsing it through a homemade RunRev program that, in essence, loads each pano, spins it to the recorded values and takes a snapshot into a JPEG file.
