Why Captcha (security image) doesn't work?

First, please make sure that you have completed this step after Dolphin installation:

I am in China,But I can't use Captcha!

What can I do to fix it.

Maybe ask AndrewP if his mod works in China:

I found this for you also:

Looks like a free way to add playthru captcha working in China.

I was struggling with this and it just resolved itself. I got the captcha working, but it gave wrong answers. I was trying to get it working for the 'Join' function. 

I found to get it working correctly, I needed to add the entire end of the URL, maybe plain for others, but stumped me.

I had the '/dolph: Join' in there, but needed 'dolph/join.php: Join' in the google page to get it working correctly.

I hope this helps someone else.

Something I thought it was was in the google code- some characters look like numbers but are letters. ie: What looks like '1' is a lower case 'L'.
