We've caught a few school policy violations by pure luck when glancing at the thumbnail previews.
Moodle used to have a www.moodlersiteurl/USERPIX URL that would show all of the current user profile pictures in an array on a single web page. It would be awesome if we could see all current thumbnails for all computers in one web page.
A quick glance at all of them would be beneficial to us K-12 tech guys trying to control the inappropriate use and probably to other companies.
