Force img tag to be https on https site

[NicholasJohn16]

Is there anyway to force the img tag to use https when accessing a site over https? A few of my users are using non-secure links and I'd rather the images just not work on https then transfer insecure images.

Would an agnostic // URL work for you?

If someone visits the site on http and the img link is https, (like if its hosted at imgur.com which defaults to https) I wouldn't want that downgraded to http.

My thinking was that it'd be best to just force https in certain situations. I could handle checking if its https if there was just an option for the imageFilter that allowed for https to be forced.

Sounds good. Feel free to submit a PR.
