Please make sure you have added the "Now Playing" Newsletter to your email provider's "safe list." This action will allow you to click on links and download pictures upon receipt of the newsletter.
You can typically do this through the notification from your email service provider at the top of the newsletter email, from your email service provider.
If you have already designated the newsletter as "safe" and the links still aren't working, then click "view email in a browser" at the very top of your email above the "Now Playing" logo.
