title: Jquery: Hide all images except recaptcha image
body: <p>i need a code in Jquery for hide all images on all pages except the 'reCaptcha' thing.
  The images of reCaptcha start with the link: 'google.com/recaptcha' or 'recaptcha.net' ...
  My idea is to make the script that hide all images but not touch the images that contains the part 'recaptcha'. 
  Is possible to make in Jquery?
  Thanks in advance and to all.
  Kind Regards.
  Luca.</p>
