Template: Ability specify KCAPTCHA background colour

[harikaram]

Either  via <IMG> url query string, like (in tpl_form.php)...

Code:

<img ... src="<?php echo $link; ?>?bgcolor=FFA3E4" />

Or in the general configs (or both!)

Gratefully,

You can setup this in /components/com_jcomments/libraries/kcaptcha/kcaptcha_config.php:

Code: (php)

$foreground_color = array(180, 180, 180);
$background_color = array(246, 246, 246);

Or you want to have a way to override the default KCAPTCHA's settings from template?

[harikaram]

Either the template or the config settings as I use a centralised Joomla installation for multiple sites and changing the kcaptch.config.php file would change it for all of them!

As kcaptcha_config.php is included directly from kcaptcha.php we can't override kcaptcha's variables. I see only one way - to modify kcaptcha_config.php and take current bgcolor value from some request variable. Or you have more correct idea? I do not want to modify KCAPTCHA library so the solution must not change kcaptcha.php...
