Download using wget to keep metadata.
A picture metadata can change, example dates, if you download a picture directly from a browser. I recommend downloading the content using wget.
Download from browser
1. In this case we can see a recent date (File modification date/time)
- ls -l needle.jpg
- date
- exiftool needle.jpg
Download using wget
1. In this other scenario, the last modification time will show as the original. An older date.
- wget http://10.10.10.115/needle.jpg
- ls -l needle.jpg.1
- exiftool needle.jpg.1
