You may have noticed that I don't post pictures. If not, now you know.

One of the reasons is that I'm worried about sharing meta data.

Does anyone know:

1. Does the Lemmy software strip / hide meta data from photos when they're uploaded?
2. Is there a way of stripping meta data from photos?
3. Does downloading an image from the internet and uploading it from my hard drive add any meta data?
4. If I create a digital image, does it have meta data that could reveal my location, etc? (And then questions 1 and 2 for this option.)
5. How should/could I keep my data/location safe if I choose to post either my photos, my scans, or pictures (either created by me or downloaded from the internet)?
