But you do have a C compiler, right?

CLC in a nutshell.

I just tested the Python script and found it works perfectly fine on my
system, so thanks for making this available.

I would just like a slightly different filename result.

To use one example, if an image named 'img_9424.jpg' exists in the
directory, a sub directory will be created in Exif_out/20100521 as the
picture was taken according to the exif data on 21st May 2010. The image
file itself is then named to '20100521_150221__img_9424.jpg'. In other
words, the new filename reflects not only the date but also the exact time.

Using the Python script, as it currently made, is it possible to keep the
image name unchanged? I mean so that img_9424.jpg will not include the
prepended parts prior to the old filename. As the Python script places
relevant images in sub-directories by date anyway there is no risk of
conflicting image names on any one day. The camera I use will not reset its
count procedure to take two different images named img_0001.jpg on a single
day, at least not without taking over 9999 images in the one single day.

Alternatively, how can I batch rename images in a working directory
according to a regex that simply removes the characters prior to and
including the first two consecutive underscores found in the filename?

In other words, for the image named: ..
20100521_150221__img_9424.jpg

.... a (sed/perl/shell/pything) script or command would rename the image to
'img_9424.jpg'.

Many thanks for any tips how this may be done.

Sure. I had put that info in because my sister and brother-in-law had
pictures from multiple cameras. So including the time allowed them to see
the pictures in the correct order, regardless of the source camera. And they
could then also group pictures of multiple days in one single dir (eg: a
holiday trip) and still keep some order. It also allows to collect pictures
in one dir on a CD-rom to be sent to the print shop, without the risk of
colliding names.

A new file (exif_tuxedo.py) if now on the server. Just run that.

I _told_ you to run it on a test set. :-)

I'm sure someone can come up with a script for that. Doing it in Python is
trivial, but I'm running late for work as it is. :-)

If you get no solution, give a yell.

I see the point. I also have two different cameras so your original version
will be helpful on other occasions.

Many thanks for the tuxedo version of your directory creation and image
reorganisation by exif date script! I now have two options and I will
probably make regular use of both versions.

Indeed I found a simple solution in a later post. I just didn't want to
tamper with your python procedures in case I'd brake something.

I'm all set, my batch of 5000+ holiday images are neatly organised by date.

Thanks again!
