The image of the captcha is not showing properly. This is on

Fixed. Needed a specific configuration for nginx. 

Solution found at: 
http://www.mail-archive.com/heroku@googlegroups.com/msg06836.html

simple_captcha uses send_file to send the image to the browser, so you need to 
enable XSendfile in the production environment (environments/production.rb) 
with:

    config.action_dispatch.x_sendfile_header = "X-Sendfile"

Nginx uses X-Accel-Redirect instead, so the solution is a bit different. See 
http://wiki.nginx.org/XSendfile

    config.action_dispatch.x_sendfile_header = "X-Accel-Redirect"
