csonnek on "[Plugin: Jetpack by WordPress.com] Featured Image not working with Related Posts"

Thanks for the report! I had a look at your site, and noticed that Jetpack is having trouble connecting. That's likely responsible for the trouble with your missing images.

While your site is publicly accessible, we cannot access your site's XML-RPC file:
http://jvkrakowski.com/xmlrpc.php

This file is used by Jetpack and other plugins and apps to connect to your site, and must retu the following message:

XML-RPC server accepts POST requests only.

Since your site retus a "403 Forbidden" error for this page, I would recommend that you check the following:

1) Can you see the /xmlrpc.php file at the root of your WordPress installation when accessing your site via FTP?

2) Do you use any security plugins that may block access to this file? If so, could you try to disable them?

3) Does your hosting provider block access to this file? If you don't find any plugin that may block access to the file on your site, I would recommend that you get in touch with your host.

After you resolve the issue above, you can try connecting Jetpack again. Then, see if the issue persists.

Please let me know how that works for you!
