   First off, my thanks for a great form tool. I've been looking for something like this for a long time.

   I want to change the background and text colours in the captcha image. e.g Navy blue text on a pale green background .... Is this possible?

   If so, where would the changes be made??

   Thanks,
   Ron S

   Ron,

   You will need to edit hooks/custom_hooks.php and define your theme there. At least I believe you can still do this there, I haven't done it in a while though.

   Check out http://recaptcha.net for further info on themes.

   Hope this helps!

   Hi Saghalie,

   Sorry, I didn't think to say it in my original post but I'm using internal Captcha.
   I don't think this is very similar to recaptcha?

   Thanks.

   Well ... if it's of interest to anyone else, I did find the solution to this. The CAPTCHA image is available in glorious colour by making the following change:

   ./lib/php-captcha/php-captcha.inc.php

   look for " // class defaults - change to effect globally "
   change define('CAPTCHA_USE_COLOUR', false);
   to define('CAPTCHA_USE_COLOUR', true);

   To see an example check out my test form at www.callsave.com.au/secure_form.php

   Regards,

   If you need to use single color for the text.
   Let say we would like to have:

   Blue text: 003399
   Green background: 00FF00

   (taken from http://html-color-codes.com/)

   Edit your php-captcha.inc.php, search around line 272 for this code:

   $iTextColour = imagecolorallocate($this->oImage, rand(0, 100), rand(0, 100), rand(0, 100));

   change it to use the blue color:
   

   $iTextColour = imagecolorallocate($this->oImage, 0x00, 0x33, 0x99);

   Next, search around line 211:

   if ($this->bUseColour) {
       $iLineColour = imagecolorallocate($this->oImage, rand(100, 250), rand(100, 250), rand(100, 250));
   }

   change it to use the green color:
   

   if ($this->bUseColour) {
       $iLineColour = imagecolorallocate($this->oImage, 0x00, 0xFF, 0x00);
   }

   That would set your colors.

   @ Ron S

   Can you tell me if the internal Captcha is available to use in MatchForm? If yes any special place I would look to set this as the default for my forms. reCaptcha seems to be much to difficult to "answer test" for me.

   Thanks,

   yes howard, you can use internal captcha in machform, simply edit your config.php file and you will find this line :

   define('USE_INTERNAL_CAPTCHA',false);

   set it as true
