Function sortByKey
sorts the found albums (images) by the required key(s)
NB: this sort is sensitive to the key(s) chosen and makes the appropriate sorts based on same. Some multi-key sorts will not make any sense and will give unexpected results. Most notably any that contain the keys "title" or "desc" as these require multi-lingual sorts.
