I ended up skipping over this chapter. After some mild research, there are quite a bit of websites (Google and Amazon for example) that disabled us from pulling images from them. I did find some random websites were this did work though.

I found the answer to this in another thread.

change the forms.py as follows.
Add the the certifi import
import certifi
change the urlopen call to as below.

response = request.urlopen(image_url,cafile=certifi.where())
