Ask HN: Can Facebook access iPhone photo without user uploading them to Facebook?

This could be very much a rare coincidence. I saw Facebook advertising Sphero BB8 right after I took photos from my iPhone. I did not upload these photos to Facebook or post comments on Facebook regarding BB8. Is Facebook accessing iPhone photos without permission and uploading them for advertisement purposes?

Those who are interested in trying out. Please take a photo of well known product ( BB8, Lays Chips, Parrot Drone etc) but don't upload it to Facebook or don't post any comments regarding these things on Facebook. Check if you see advertisements regarding above items in your FB feed.
