Command-Line - Editing images
Using this script (https://github.com/TheOuterLinux/BitChuteNotes/tree/master/Command-Line/09%20-%20Command-Line%20-%20Editing%20images%20in%20the%20command%20line), you can edit images easily in the command line. Dailog as an interface allows keyboard, mouse, and space bar for auto-completion. If you are in GUI, images are previewed with your default viewer; if you are in TTY, fbi (frame-buffering image-viewer) is used. This is not for batch editing.
