Hi  
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://  
[rubyforge.org/var/svn/expressica/plugins/simple\_captcha](http://rubyforge.org/var/svn/expressica/plugins/simple_captcha)

_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?  
end
