Remove location data
Privacy is important, but the modern world proves some really useful tools in attaching tracing data into things like images so that when you find a photo in a directory many years from now, you can place it to a point on the earth with a time stamp.
So, how do you tally these two contradictory needs? Well, I keep my original photos and publish versions that have the location removed.
Linux is your friend here, with a tool "exiftool".
Find files with meta data
exiftool -gps* */* > myList
Produces a "myList" of files with the meta data. I tend to lose the other files I am not interested in, but that's to preserve them as much as possible!
Remove the meta data
cd to_directory_with_images_with_meta_data_to_remove
exiftool "-gps*=" *
cd ..
Work through all the directories. exiftool retains the original, so go and remove these once all the files have been processed.
rm `find . -name *_original`
Now copy over the new files to where you are publishing them.
