graphics based content filter

Hi,

Is there a good graphics based content filter that will
automatically
prevent the browser from displaying certain images based on
flesh tone?
We are concerned with blocking pornographic images. Is this
possible?
Blocking pornographic text is not as great a concern for us.


Also, we are hoping to do this at the client side rather
than through
the use of a proxy server.

Has this type of filtering software been largely
discredited, or, are
there solutions out there worthy of consideration?

I would welcome any suggestions.

Regards
John
