Just by chance, I saw one of my pictures on someone else's blog, unacknowledged, without my permission. Folks, this is not right. In the words of Kevan Atteberry, "What would your mother say? Hmmm?"
As I am fond of saying to my own children, "Do the right thing, even when I'm not watching." This is good advice for adults as well.
Fair use means taking without permission. But it doesn't mean not to acknowledge the source. Please folks, always, always acknowledge your source. As a writer of nonfiction, I am highly aware of this. The source of every quote and fact I choose to include in my article is meticulously recorded should I need to refer to it. Plus, it allows my readers to go further with their own reading, should they choose to.
I enjoy taking pictures. I'm not a professional but I've been complimented many times on the pictures I've taken. It makes me feel good to share a few images from my life. Why would anybody want to take them without acknowledging the source? And it's all the more distressing that it's another person in the business.
Do the right thing. It's easy.
