### Oziam Captcha Class by Dwayne Rothe ###
###########################################

This class is a simple captcha class to make sure your emails are coming from real people and not bots.

This is a quite simple class with minimal code and overhead, you can customize just about everything very easily by editing the captcha_class.php file giving you a totally unique captcha image with refresh capabilities.

You can edit the background image which supports gif, jpg and png files, font type, text size, text colour, text skew/angle, text length(number of characters) and even add random dots to the background(optional).

This file includes everything you need to implement it into any website form using php including a simple
example form to get you going.

### Installation and Testing ###
================================
Upload everything in this folder(except example images) to your server in binary mode.
Navigate to the example.php page, you should see the contact form, now you can test it with different backgrounds and fonts etc...

When you are ready to use on your site just copy the relevant form fields and code to your contact form.

Please note:
This file should include example.php file, 2 example images, captcha folder containing 3 background images, jokerman.ttf font file and captcha_class.php class file. Sometimes the font file will be removed by file repositories, in the event of that happening you will have to add your own font file to the captcha folder, 
we recommend jokerman.ttf as this looks quite unique with its jaggered type letters.

### Troubleshooting ###
=======================
If all you see is a blank image placeholder, check the background image and the font file are included
in the captcha folder and that the path is correct relevant to the captcha_class.php file.

Have Fun!

If you would like me to see your form in action or you cannot find the jokerman font send me an email!!

Cheers!!!
