[wxpython-users] where we put the .png files?

[Tim van der Leeuw]

os.argv[0] gives you the full absolute path to your application. So
you strip the filename off using functions from os.path module, and
load the pictures and other files from the application directory (or
subdirectory thereof). Works for me ;-)
