               add--> , "rb" <-- here ^^
to make it
im = Image.open('backgroundimage.gif', "rb")

else it won't work on MS Windows or Macs.

Replace this with

sys.stdout.write("Content-Type: image/gif\r\n\r\n")

because print adds its own "\n" after it prints
the text.

>sys.stdout.write(sfp.getvalue())
