The small images you put on buttons and such are nice, but a real pain if you have to attach all those image files to your program. Python's base64 encoding module makes it easy to convert the binary image code to a string that you can simply make part of your program. Here is an example how to do this using the Tknter GUI toolkit.
# use a base64 encoded string of a gif image in Tkinter
# (base64 converts binary data into string characters)
# good for small images, avoids having to send the image file
# the image string is created with the following simple
# Python code and is then copied and pasted to this program
# (tk only uses gif, not all gif formats work properly!)
gif_file = "grape.gif"
print "grape_gif='''\\\n" + base64.encodestring(open(gif_file).read()) + "'''"
# tested with Python25 EU 2/20/2007
import Tkinter as tk
root = tk.Tk()
gif_image = tk.PhotoImage(data=grape_gif)
b1 = tk.Button(root, image=gif_image)
# save the button image from garbage collection!
b1.image = gif_image
