Using zend_captcha_image extends we get the final image, which is stored on the server.
Is there any ready-made solutions, but do not delete the file when it is evaluated that do not create a file with the captcha?
Recaptcha does not offer.

In zend_captcha_image extends there is a setting responsible for the storage of these files.
\r
 /** * How long to keep generated images * * @var int */ protected $_expiration = 600; 

the next generation pictures she cleans obsolete old files in the store folder
