Like many people, I use Wikipedia as my starting point for all information.
Over the years I have come to depend on Wikipedia. Often using Wikipedia to help build the foundation for my classes. I use Wikipedia so much I first got involved with editing and updating incorrect information. Which was followed by adding new content and having my photography accepted.
A photograph say a million words. Having Wikipedia accept my photography is a great horror.
Here are some of the images that are being used by Wikipedia.
