Strange, if I do

$ python3.2 counter-vertically-WORKING.py

it prints all results and also creates all txt-files:

$ ls *.xpm *.txt
ss_0.txt  ss_0.xpm  ss_1.txt  ss_1.xpm  ss_2.txt  ss_2.xpm

Please insert "print(fileName)" as the first line in your main for-loop 
so we can see on which file the program hangs.
