Yep, and my site includes photos from S3, and S3 can't be https (because my bucket name has periods in it, like Amazon suggested). I guess I'll have to proxy the images myself.
It's kind of sad that people, and amazon itself felt the need to push towards that... Of course Amazon is big enough at this point, they could/should have their own intermediary setup (like cloudflare) for use with s3.... Of course they probably just want to make the money from cloudfront.
