File ➤ Export as /tmp/ShowAuthor.jpg

Then in a terminal:

Code:

➤ exiftool /tmp/ShowAuthor.jpg | grep Artist
Artist                          : Someone Else

QED

Great work! Will this work as a plug-in with BIMP? Also is the XML version of the Copyright tag just "Exif.Image.License"? If not where can I check those properties?
