I was looking at the wrong file previously, and got mixed up, doh!
I have installed the Adafruit_Python_SSD1306 library now.

(There is no mention that I can see about installing other libraries etc 
to get the project to work, by the author)

I had to make some changes in the authors file here:

import time
import Adafruit_SSD1306
import RPi.GPIO as GPIO <<<<here
from PIL import Image   <<<<here
from PIL import ImageFont <<<<here
from PIL import ImageDraw <<<<here
import os

Due to
import ImageFont
ImportError: No module named ImageFont

etc

Now I get these errors:

pi at raspberrypi:~/Downloads $ python Internet.py
Traceback (most recent call last):
   File "Internet.py", line 164, in <module>
     disp.begin()
   File "build/bdist.linux-armv6l/egg/Adafruit_SSD1306/SSD1306.py", line 
148, in begin
   File "build/bdist.linux-armv6l/egg/Adafruit_SSD1306/SSD1306.py", line

   File "build/bdist.linux-armv6l/egg/Adafruit_PureIO/smbus.py", line 
268, in write_byte_data
IOError: [Errno 121] Remote I/O error.

Maybe I have created these errors unknowingly by the said changes I made.

Thanks
