it is only possible to rotate and rebuild/remove embedded thumbnails,
it would be handy to have extract/replace actions as well

  • add new commands for embedded thumbnail
    • extract
      exiftool -a -b -W FOLDERNAME/%f_%t%-c.%s -preview:all FILE
      exiftool -a -b -W %f_%t%-c.%s -preview:all test_img_thumbnail.jpg
    • replace
      exiftool '-ThumbnailImage<=SOURCE_FILE' TARGET_FILE
      exiftool '-ThumbnailImage<=new_thumb.jpg' target_img.jpg
      to comply with standard, new thumbnail must be ≤64Kb
    • remove
      same as in Clean... dialog, eg
      exiftool -ThumbnailImage= FILE OR
      exiftool -ifd1:all= -ext jpg FILE
      check link for details
