SSL enabled sites require *everything* that is displayed inside of the page to be served from SSL. If the page is SSL (see the lock at the top) but one of the images that you're viewing in the page isn't being served over SSL, then the browser warns you that the page isn't 100% secure.
Since our members embed images into their posts, we can't control whether or not those links are served from an SSL site (e.g.
https :// imgur. com/image123.jpg vs
http: // imgur. com/image123.jpg). In order to ensure that every link displayed is SSL our server now fetches the image from the remote server and caches it on our server...and serves it to the viewer using our SSL certificate.
You can view this post to see this in action...

The original image embedded in this post was hosted here...
http: //i. imgur. com/sRTBcu0l.jpg (link intentionally broken so as not to embed the image)
If you view the post now you'll see that image served from a URL like this... (again, intentionally broken)
https: //www. pilotsofamerica. com/community/proxy.php?image=http%3A%2F%2Fi.imgur.com%2FsRTBcu0l.jpg&hash=bf3870e07c8ce53a1b8c620f69c5007a
So we're fetching the image and making sure that it's served from our server.
