What you will do when you need to manage all your Image files according to what they shows/represent, I am not talking about you, what I also done in past, just select Image files one by one create folder for that kind of Image files and paste into that folder.
Now Using this application you just have to define from which PATH you want to work with your Image Files and that's done, and define possible categories for Image files and use your Num-pad keys from 0, 1, 2, 3, and so...
