Why do I license all my photos Creative Commons? Because I have been part of public service websites which depend on these photographs for illustrations, particularly wikiHow, which is very grateful to those who have generously provided some of their work. I thought I might as well add to the pool of what can be used by sites which are so useful to the world. After all, I don't plan on marketing my work, but my work does have value, and I am more than happy to share that value.
I have enabled tagging by the public, so that anyone dropping by can add more tags to any photo, which of course helps those who need Creative Commons photos to find what is useful to them. So tag away!
If you are going to use one of my photos, please link to the photo used, please indicate that the photo is used Courtesy of Ivydawned through Creative Commons (linking back to my profile page if you can work that out). Also, please link to the CC license, which typically will be creativecommons.org/licenses/by-sa/2.0/deed.en
