Keyimage
Keyimage is a small application, useful for organizing pictures. Point it at a directory containing image files, and it will display one at a time, allowing you to classify each with a single key stroke. When you are done, keyimage will move each image to a subdirectory according to which key you classified it with.
For example, let's say you have a directory containing pictures of three things: cats, landscapes, and delicious cakes. You decide ahead of time to use the letter 'c' for cats, 'l' for landscapes, and 'd' for delicious cakes.
So you open keyimage and select this directory. Then each time you see a cat picture, you press 'c', and so forth. When you are finished the cat pictures will move to 'keyimage/c/', the landscapes to 'keyimage/l/' and the delicious cakes to 'keyimage/d/'.
That's it!
Special key commands:
'enter' to finish early (unseen images stay where they are) 'backspace' to go back to the previous image
Command line options:
'-d <directory>' to specify a directory
