Berthold Stoeger 23d38a982d Dive pictures: give user option to recalculate thumbnails
Even though hashes of image contents are calculated, the hashes are
not compared to actual file contents in routine-operation. Therefore
give the user the option to recalculate thumbnails, should they have
edited the picture.
