Question

I’d like to have a link under simple_captcha image. Click to link should reload simple_captcha image. I can’t find in gem any information about it. How can I update it? Thanks for advance.

I have also faced the same issue then after i find the solutionas mentioned below .
As i have used jquery to refresh the captcha div this is the javascript code i have used to refresh the captcha .

$(document).ready(function() {
  $(".refresh_image").click(function() {
    $('#captcha').load("/users/dashboard/refresh_captcha_div");
  });
});

After this put the view page codes for captcha in a partial file and render the partial everytime when the refresh div (any link or button) is clicked by the above codes pasted . It will call a action there you need to render the partial only . (here refresh_captcha_div in users/dashboard controller). below are the view files codes of mine for reference .

       <div id ="captcha">
         <%= render "simple_captcha_institute"%>
       </div>
         <%=link_to (image_tag "/assets/refresh_image.png"),"#", :class => "refresh_image"%>  

This is the view page codes where i am rendering the partial and then the codes in the partial are

<div id="refresh_captcha">
  <%= show_simple_captcha(:object=>"institute", :label => "Type The Above Characters..") %>            
</div>
