Hi Suresh,

     You can simply refresh your image pointer. Through Ajax you need to provide the image pointer on click of some button where you can change only the captcha image without refreshing a page.

Hi Suresh,

      You have to take image names in an array if they are fix and randomly select them while refreshing the image script.
