The "Thank You" is due from me. That thanks goes to the many volunteers that I worked with at Wikipedia and Citizendium who have provided the images for this site and whose efforts have helped educate many people in the world.
Most images have been uploaded from Wikipedia Commons and are, to the best of my knowlege, free of copyright restrictions. They have been provided by dozens of philanthropic contributors - and made available to others.

Thank You Wikipedia Commons!
Some articles have been uploaded from Citizendium, where I was their primary author, or one of many collaborative authors. The folks at Citizendium taught me quite a bit about copyright concerns and public presentation of ideas - for which I am very grateful. Some images used in articles here are original or copyright free materials from the Citizendium, provided by philanthropists of intellectual wealth.
