The coolest Thing so far is Flickr. I may upload all my personal photos, as a backup, and for sharing with family. I found a photo on Flickr that was posted by jacqueline-w. It is just a picture of a leaf, but for some reason, it's relaxing to me. I enjoyed doing some searches and was amazed by how many pictures came up with my specific searches.
I did create a Flickr account and uploaded one of my own photos. Very easy to use. I have been using Shutterfly as they are associated with Target, and I can pick up my prints in the store.
