# files:

   1. gotcha.php 					- Contains the class definitions
   2. captcha_image.php				- Image generation script
   3. index.php						- Usage example
   4. util.php						- Contains constants definitions utility functions
   5. arialbd.ttf					- font file
   6. SFTransRoboticsExtended.ttf	- font file

If you just upload these files in to a sub directory on your site e.g.www.yourdomain.com/gotcha 
point your browser to www.yourdomain/gotcha/exemple.php you will see a working exemple.

			SUGGETED SETTING

# Move captcha_image.php to your image directory. Rename it if you want.
# Move gotcha.php, util.php and the two(2) font files in a directory outside you web directory.
# Considering the following directory structure.
    	 /home
         	/gotcha
          		.gotcha.php
          		.util.php 
          	/fonts
          		.arialbd.ttf
          		.SFTransRoboticsExtended.ttf - font file
          	/www -Your web directory
               	/images - your image directory.
                 	.captcha_image.php

# Edit captcha_image.php. 
	On line 32 and 33 change the include directive to reflect the location of gotcha.php and util.php. e.g for the above exemple it will look like this:
			include_once('../../gotcha/gotcha.php')
			include_once('../../gotcha/util.php')
	or like this:
			include_once('/home/gotcha/gotcha.php')
			include_once('/home/gotcha/util.php')
	the first one is more flexible.
	
	On line 64 change:
	$t->addFont('SFTransRoboticsExtended.ttf') to $t->addFont('../../fonts/SFTransRoboticsExtended.ttf')
	On line 65 change:
	$t->addFont('arialbd.ttf') to $t->addFont('../../fonts/arialbd.ttf')
	
	- To add more fonts, just repeat this process with different font files.
	
# That's about it. See exemple.php for usage exemple.

#SECURITY BEST PRACTICE.
It is recommended that you change the value of the following:
 *CAPTCHA_SESSION_KEY -A constant declared in util.php on line 2. The current value is "G0TCHA_CAPTCHA".
