Does anybody know a reliable and standard way to write keywords into images?
I tried different ways and ended up
to choose Exiftool for several reasons
Before I looked at GD and Imagick. GD can only read EXIF. Imagick could not be "convinced" to write the "subject" in a (standard) way Darktable or Exiftool would do it.
