There are three views of photo on facebook: "Photos of you", "Photos" and "albums".
Albums can be reorder by the user just by dragging them around.
Photos seem to be order by the date they were taken.
Photos of you seem to be be ordered based on the time of upload and there seems to be now way to move them around. I recently uploaded some photos that are 10 years old and I do not want them on the top. Is there a way to achieve this?
