I found the issue: it is the path to the image. When I change the problem
line to
image = Image.open(os.path.realpath('C:\Users\Lloyd\Desktop\Lloyd.png'))
it works, but I cannot hard code the path and I cannot predict where the
user will try to upload a file from. Isn't there a way to dynamically get
the path from the file upload dialogue where the user browses to it and
selects it?
Thanks...
