## Author Notes:
##
## This patch to phpbb2 adds a new kind of Visual Confirmation,
## also known as a CAPTCHA. The person registering for an account must
## look at photographs and determine if they are photographs of animals
## or not.
##
## The captcha can be broken by a bot that has a copy of the photos. To
## do this, the bot must compare the presented images to the photos in
## the distribution. To make this a little harder, the mod randomly
## tweaks the gamma and randomly crops the images before presenting them
## to the user. Therefore, comparison requires more than a simple
## bit-for-bit equality test. This isn't a very strong protection,
## but it's better than nothing.
##
## The real strength of the captcha, however, is the fact that it's so
## easy for the board admin to replace the photos. A bot that doesn't
## have a copy of the photo library is at an almost crippling
## disadvantage. Once the photos have been replaced, this captcha is
## almost unbreakable.
##
## I have made it as easy as possible to drop in new photos. As you
## can see, there are two directories containing photos:
##
## images/captcha/animal
## images/captcha/non
##
## Which contain, respectively, animals and non-animals. All of the
## supplied images are 256x192 --- this is the optimal size. However,
## you can use images that are somewhat smaller or larger. All images
## must be jpegs. The filenames do not matter, although the extension
## must be jpg. It is recommended that the board admin delete all
## the supplied photos, and replace them with photos of his own.
##
## The supplied photos are kittens and cars. I intentionally didn't
## use a mix of different types of animals, or different types of
## non-animals. I feel that using two clear categories makes it
## easier for the human --- it is very easy to visually scan for
## kittens, but much harder to visually scan for animals-in-general.
##
## To enable the mod, you must browse to the board configuration
## page (admin_board.php), find the entry for "Visual Confirmation,"
## and select "Photos."
##
## This captcha requires the php GD extension. If you install this
## MOD without installing GD, the board configuration page will
## display the message "If you were to install the php GD extension,
## a photo-recognition mode would become available here."
##
## The code is quite small, and this mod integrates the new CAPTCHA
## cleanly into the phpbb2 2.0.21 codebase. It is my hope that the phpbb2
## developers will eventually include this mod with the distribution.
##
## This software is actually in the public domain, but the format of
## the license field above doesn't provide any means to specify that.
## Long story short, you can do anything at all with it.
