You can remove all the regions from a pic by doing:
exiftool -regionlist= myphoto.jpg
Exiftool is free.
oh yes my bad, i meant exifcleaner is paid software...
i think your way does what i want to do but i dont know how to use the exiftool, specially since i have 20'000 pictures where i want to remove that region thing,
could you help me and if it's possible with the exiftool GUI =)
It's probably possible with Exiftool GUI, but I've never used it.
To process a folder or folder hierarchy of pics, you would type the following command line:
exiftool -r -regionlist= full-path-to-folder
E.g. on Windows, to process all the pics insider your Pictures folder, you'd run the Command Prompt and type:
exiftool -r -regionlist= C:\Users\john\Pictures
On Windows, you'd use Terminal.
I strongly recommend that you make a backup of your pic folders if you try this. While Exiftool will make its own backup copies of any files it modifies, it's a good idea to be extra careful when making mass changes. And of course, try just one or two pics first to make sure it's doing what you want.
