And for really expert shit, thumbnail manipulation:https://www.sentex.ca/~mwandel/jhead/jhead.exe
(this file is included in ExifToolGUI, but you get an older version)
To use it, make three text files, paste stuff into them, then rename to ".bat" , then make a folder named "thumbnails"
start jhead.exe -st "thumbnails\&i" *.jpg
start jhead.exe -rgt *.jpg
