Interestingly, when you double click on the placemark, the description balloon opens, and the image is loaded (the first request), then while Google Earth is zooming to the correct place, there are no more requests, but as soon as it arrives and the movement stops, continuous requests start.



Actually, the movement has nothing to do with it. It's 10 seconds after the first request, no matter what, that the continuous requests start.
