Unpack Png Files From The Plist File

first, make sure you have both the png and plist files in the same directory, in my case: freeGifts.plist and freeGifts.png

second, save the following script as unpack_plist.py

then, python unpack_plist.py freeGifts, it will generate lots of png files to a directory named freeGifts

requirement: python, PIL
