FreeBSD has an excellent tool with which you can change the size of all the photos that are in the same directory with one command. I mean the console image editor imagemagick. Install imagemagick pkg install imagemagick Then create a directory where we will put the photos we need, for example, mkdir image And we actually edit the image mogrify -resize here size, file path, file extension.
