You can take the short way directly to the picture and bypass the fancy Java:

It doesn't automatically reload like the fancy Java page but it should work.
I just set up my Linux box to save a picture every minute. Should make an interesting time lapse or blackmail photos.
If you can assemble those images into a video, I'd love to get a copy for superjett.com I wanted to bring my second netcam to save a timelapse, but just didn't bother.
