I thought this would be an easy task , but I'm mistaken  :)

I just want to know how to shuffle,  organise,  ie: "PUT IN CHRONOLOGICAL ORDER",  my own photos, within a folder .

ie:   folder named  DAUGHTER , say  I want to put the pictures in order, for instance, ages 1 -20 ,  (not by the date picture was taken )

.... in Picas 3 , I just drag and drop, ..... everytime I try that in photo gallery it won't move, just goes back to same spot .....

FRUSTRATING,   any help is good help, CHEERS.
