ps... aren't the images produced on the fly? that is probably why they can get away with ignoring noarchive, because its not archived.
The snapshots of the pages are not produced on the fly, I can definitely say that.
However, the preview image you actually see is produced on the fly because they draw an orange box around the block or blocks of text on your page that contain the search terms.
