+    Display an Image Located at a URL
+
+    Downloads and displays a PNG (or GIF) image given a URL
+    
+    NOTE:
+        Early versions of tkinter (for example 8.6.6 found in Python 3.6) have trouble with some PNG formats.
+        Moving to Python 3.7 fixes this or you can use a tool to re-encode the image (e.g. psgresizer) save it and 
+        it will then work OK in Python 3.6.
+        Example of one of these images - https://www.python.org/static/community_logos/python-logo-master-v3-TM.png
