public ActionResult Image()
        {
            var builder = new XCaptcha.ImageBuilder();
            var result = builder.Create();

            Session.Add("SecurityNumber", result.Solution);

            return new FileContentResult(result.Image, result.ContentType);
        }

i need to call this action using javascript and set the new image source any help will be good

To update an image, just update the src attribute. Using jQuery:

$("#Reload").click(function(e) {
    $("#Captcha").attr("src", "/path/to/your/action");

    e.preventDefault();
});

What this does is when you click an element with id "Reload", set the "src" attribute of the image with id "Captcha" to "/path/of/your/action". e.preventDefault() is there so we do not follow the link.

<script type="text/javascript"> $(document).ready(function () {     $("#Reload").click(function (e) {         $("#image").attr("src", "/AccountController/Image");          e.preventDefault();     });     )}; </script>

@Eslam Yes, that should work. Are you sure you want the Controller suffix in there? I guess it should be "/Account/Image".
