Here is some code that I think will help
remove(image);
imagePass = randomString(6, 8);
captchaImageResource = new
CaptchaImageResource(imagePass);
image = new Image("captchaImage",
captchaImageResource);
add(image);
you can have it inside your onClick(AjaxRequestTarget target) {}
the key point to note is that you have to remove it first from the
component.
