I'm uncomfortable about a session cookie based system for IP readers, many of our readers are in Internet Cafes and I'm not sure if PCs in those sorts of environments get rebooted and the session cookies wiped between customers.
It varies depending on the specific location - some effectively reboot and wipe the profile between users, some merely kick one user out of the seat and put a new one in without even closing the browser tabs. Same with domestic one-computer-per-household situations!
On the other hand, the proposed implementation is relatively transparently reversible - concealed images are shown as a placeholder with a trivial "click to display again" option - and this sort of "legacy filtering" should be fairly easy for a user to switch back on or off. It's not perfect, but it's probably no *less* clunky than requiring people to sign in (and the associated forgetting-to-sign-out...)
