Before deploying CAPTCHAs, please *do* think carefully about the
fact that some real genuine entirely innocent human beings cannot
cope with them.  For blocking entry to a collection of photographs,
it might make sense to use a technique that the blind and partially
sighted can't even see let alone solve; for other things there are
humane reasons not to use them.  You might even want to consider
legal advice about whether shutting the disabled out is legal in
your country.
