I’m a big fan of NextDraft, but disappointed to not see attribution of the image used here. With 3 minutes of reverse google image searching, I find it used similarly in heaps of sites, but also that it is a stock image $.
Attributing media is, IMHO, less a thing of avoiding copyright slaps, and more an expression of gratitude to photographers who openly share their work. I also recommend Mediachain as a new tool for not only finding images, but getting quick cut and paste attribution statements.
When writers, publishers, with large readerships do not provide photo credits, it signals this as an okay practice for others.
