As others have said, you don't need PIL for this one. You need to have a 
look at the data of the gfx file itself (you can do that with some 
simple Python code, though I find it easier to use a hex editor). Focus 
on the start of the data at first. Compare the patterns in the data with 
the data at the start of other image files (JPG, PNG, GIF).

 From another view of how you need to manipulate the bytes, look at what 
the dealer is doing with the cards. Count how many piles he's using.

And I guess you'll be happy to know that puzzle 13 doesn't have anything 
to do with images :)
