Export Thumbnails by Batch Script

[scharott]

Hello,
I'm not yet familiar with exiftool and Batch-programming.
I've seen the example about extracting Thumbnails file by file, but I want to do it in a directory.

I created a batch script (win-xp) with this line:

---------
for %%a in ("%converted_path%\*.*") do (%exiftool% -v0 -b -ThumbnailImage "%%a" > %batchwork_path%\%%f_Thumb.jpg)
---------

At the end I have only one file (the last thumbnail.jpg) with this name:  "%f_Thumb.jpg" in my export-directory. I think, the script will export any thumbnail, but with the same name and it overwrites the former file.

I tried it with %%%f, %%f, %%f for the original filename, but it will not accepted.

Hope you can help me, what is wrong.

Sorry, if my English is bad, but I'm from Germany and school is 40 years ago.

Thanks

You don't need a for loop.  Just do this:

exiftool -thumbnailimage -b -w _Thumb.jpg DIR

Where DIR is the directory name.

Thank you very much!

I am not getting this one ?

Does it means you get the thumbnail of  _Thumb.jpg  (1 image only) to a specified DIR ?
Even if that is so, I am  not getting it... I must be doing something wrong.

ANy way, is it possible to get ALL thumbnails of a Original_DIR to Thumb_DIR ??

Thanks
Emilio

You don't need a for loop.  Just do this:

exiftool -thumbnailimage -b -w _Thumb.jpg DIR

Where DIR is the directory name.

For each image containing a thumbnail in directory DIR, this command will create a new file called FILE_Thumb.jpg in the same directory.

Phil:

Thanks for the clarification I did not get the meaning... now it works.

But I wonder if it could be possible to create the thumbnails into a different DIR
the reasons for that is:

1) Some users do not like that I put things on their folders.. (of course I can copy them some other place and then delete them)
2) I wanted to use this feature to see the thumbnails from a memory card, and even if the thumbnails are small
   I am not sure if when the memory is full I could have problems.

Thanks

use -w SOMEOTHERDIR/%f_Thumb.jpg to write the thumbnails to another directory.

This is all explained in the -w option documentation.

Thanks  that should do the job.
