Hace un tiempo atras, Claudio subio un script en Python que permite esto:

jci@rock:~/Photos/l$ ls
IMG_1190.JPG  IMG_1191.JPG  IMG_1192.JPG  IMG_1193.JPG
jci@rock:~/Photos/l$ ~/scripts/picsdir.py .
IMG_1191.JPG
creating dir ./2011-05-23
./2011-05-23
IMG_1192.JPG
./2011-05-23
IMG_1193.JPG
./2011-05-23
IMG_1190.JPG
./2011-05-23
Traceback (most recent call last):
  File "/home/jci/scripts/picsdir.py", line 66, in <module>
    print sum(getsize(join(root, name)) for name in files)
NameError: name 'files' is not defined
jci@rock:~/Photos/l$ ls
2011-05-23

Pero desde que me dio por actualizar a Natty...

jci@socrates:~/Photos/untitled folder 2$ ~/scripts/picsdir.py  .
IMG_1101.JPG
Traceback (most recent call last):
  File "/home/jci/scripts/picsdir.py", line 64, in <module>

  File "/home/jci/scripts/picsdir.py", line 29, in move_smartly
    image = pyexiv2.Image(image_file)
AttributeError: 'module' object has no attribute 'Image'

Nada que un hack no pueda hacer :-)
