New CAPTCHA code

Pornogoddess · 2011-02-03 21:21:44

Is there a way to have different versions for the CAPTCHA code? I'm used to them and can usually read them without problem (I've usually seen them as black and white). When signing up for a user account myself, just to try it, I realized that it is extremely frustrating, and the colored background would make it next to impossible for someone who is color blind to be able to read it. Even though you can click 'Can't read it?' it takes quite a while before you can find one that you can read. I don't want my users to get frustrated by this and leave.

Edit config/captcha.php and replace:

'level' => 'medium',

with:

'level' => 'easy',

Let me know if that helps.

how do I remove the background color?
I wish it were black and white.

Well i suggest to be very carefully with making the captcha too easy to read. Humen can identify it and once you had to remove about 16 k topics / posts made by a bot u know why i warn

Hi MS_DA I do not intend to remove the captcha, I just want to change the background color to get better at reading.

Hello, I am a person who likes to collaborate with others.

I changed the captcha code for a more complete version that I used in my old script.

In this version you have control over the amount of characters you want to display your username when you register it on the site.
You can also control the background color.

Below is the source code.

You should put it in config / captcha.php

Ok good job to all
