Although not required to let the author of the photo know that you used their work, it might be a nice thing to do by leaving a comment at their Flickr or blog page.
You may also want to share to expand your "open" network using social media, eg. "I found the perfect @creativecommons licensed photo for my post on LOLCats using @Flickr!" or "I found the perfect #publicdomain photo for my textbook @Wikicommons thanks to a #schoolofopen challenge @P2PU". Many people are interested in how to find and reuse photos, and sharing the story behind your own search is sure to solicit some excitement.
Lastly, share your thoughts on the process of finding and attributing a photo here. What did you learn? What did you find frustrating? Do you have feedback for how this challenge can be improved?
