Are you talking about captcha??
If yes, then it is not possible to get text of captcha, it is provided to avoid automation.
To automate captcha you need human interaction.

Thank you rohit.But i have one doubt that In selenium it is not possible to capture image details automatically when recorded,because it changes for everytime when we run the script.
