I am using the latest release.
I have both Captcha and Akismet turned on. Any way to strengthen them? Which has more impact - Akismet is catching stuff. Not sure if Captcha is as strong as it can be. Can it be strengthen so the image is modified - more text? Or more lines?
Any ideas? I have comment approval turned on - but have to always clear lots of spam every day before I get to the real user comments.
Thanks
Jim

You can tweak the captcha settings in captcha.php - see include/captcha.inc.php for descriptions of the settings.

Thanks
I see this line in Captcha.php:
$oPhpCaptcha = new PhpCaptcha($aFonts, 150, 30, 5, 20, false);
What are the parameters for - the 150, 30, 5, 20 and false?

As I said, descriptions of the settings are in include/captcha.inc.php
$aFonts, // array of TypeType fonts to use - specify full path
$iWidth = 200, // width of image
$iHeight = 50, // height of image
$iNumChars = 5, // number of characters to draw
$iNumLines = 70, // number of noise lines to draw
$bCharShadow = false, // add shadow to generated characters to further obscure code
$sOwnerText = '', // add owner text to bottom of CAPTCHA, usually your site address
$aCharSet = array(), // array of characters to select from - if blank uses upper case A - Z
$sBackgroundImage = '' // background image to use - if blank creates image with white background

sorry my mistake - thanks for the help.
