Instructions:
You need to install action Revnart_DVD.atn in Photoshop.
[ How to install actions ]Then open Revnart_DVD.psd file and import your images there, you will need two images, one for front and one for side of the box. Put them into "[ images ]" group and run the action by pressing Shift+Ctrl+F12
Photoshop will cut images automatically so you don't need to be precise

Just remember to put layer "front" lower than "side" layer
