[Sorry about that, our housekeeper while cleaning the keyboard.]
I have just uploaded mediabox to the storage section. You can download it from here: http://www.openacs.org/storage/download/mediabox.tar.bz2?file%5fid=2554866 (just to show what I mean by "radical" as discussed in this thread: http://www.openacs.org/forums/message-view?message_id=2554034)
Have a look at the www-pvt/index.tcl file (50KB). It is also useful for everyone that wants to see how the preview of the items is done.
