time to ditch flickr then? as I have the prime membership at amazon? wish I can import flickr into amazon somehow.

on the other hand I hope they support client-side encryption so someone can only view the pictures after they're decrypted

This isn't really the same as Flickr though. It's photo backup.

For that, it may actually be better than flickr in that it apparently supports the major raw file formats including DNG.

However, it doesn't seem to be designed for any sort of photo sharing (although you can access photos remotely yourself).

Bottom line is that, if you're just using flickr for backup then, yes, something like this is probably a better match. On the other hand, if you use flickr as a photo sharing site and the backup is at least partially incidental, then I'd probably stay with flickr and maybe use both.

I have a flickr Pro subscription but I don't really view it as a backup system although having an additional set of (JPEG) backups of my favorite photos is a nice side benefit.

how to define "picture", can I hide my files into some picture then upload it and essentially use amazon-picture-unlimited as an unlimited file storage?

While I haven't read Amazon's terms of use as to whether this is ok from a policy perspective, most back-up services don't check for "files within pictures". In fact, the hiding of data within imagery is called Steganography: https://en.wikipedia.org/wiki/Steganography

Although the intent with Steganography is (weak) cryptography, the method should work for your purposes; only way to know is to test it! Admittedly until you've tested this thoroughly, I would not RELY on this for anything other than a fun test. Enjoy! :-)
