I think you want to read captcha image
If thats your requirement

you have a plugin for captcha integration

From your application root, you can run:

ruby script\plugin install svn://

*In Your Code:*

To show a captcha in your view, just use the following tag:

<%= show_simple_captcha %>

 In your controller to validate:

if simple_captcha_valid?

I think he actually wants to crack a captcha, by reading the letters
inside the given image.
