Blocked mixed content
Browsers like Firefox, Opera, Chrome or Safari block content loaded from a source different than the website you are visiting.
If you use Opera, you will see a "Unblock content" button in the navitagation bar. Cliking on it will dowload the content.
On other browsers, you may need to open the Inspect console (by right clicking somewhere in the page and selecting 'Inspect page') and copy-pasting the blocked URL in a new tab.
