Media link previews wont's show for non-https links

Now that the forum is SSL secure (HTTPS), media links for sites that are NOT https won't show as previews, for example BBC articles, because the BBC site is not https. Only the link will show.

On the other hand, sites that use SSL will show up as a preview if it's considered as media (a video for example).

On Facebook, when you post a link on your page, whether that be a video or simply an article link, a preview is generated as per these images. I particularly like this feature as it gives the link some life. IE, you get a thumbnail preview and some text as to what the link is all about, which makes it much more inviting to go to.

I'm currently hounding some of the devs at WoltLab (the software company that developed the forum software) to come up with a plugin which will add this feature, so I'll keep you all posted.

This is the technical explanation of how it's done.
