Re: iPad photos (OT)

[Sam Partington <sam.partington@xxxxxxxxx>]

Do you know if it is the filesystems creation date / time, or the meta
data
(EXIF) date of the image?

If the former then the following python script will work.  You need python
installed and for the creation times to work correctly you need the pywin32
extensions for the creation date to work on windows.   If the latter then
the solution is not so simple.

e.g. python set_image_dates_by_name.py . sorted_for_ipad

Copy all .jpg and .jpeg images in SRCDIR to DESTDIR.  The images are copied
in
name order.  The first file copied keeps it's modified time and access
time,
each subsequent file will have it's modified and access/creation/access
times
set to be one minute after the previous file.

SRCDIR must exist, DESTDIR will be created if it does not already exist.

DESTDIR can be the same as SRCDIR, though this is not recommended as this
operation can not be reversed.
