One thing I’ve tried to do has been to use public domain, CC-licensed, or my own images for posts. If you’ve paid attention to this site, I typically cycle through several images. For the Creative Commons licensed images, I was very good and added the sorts of information that seemed in compliance with the license–at least via WordPress’s UI. As time has progressed, it occurs to me that no one else can see any of that. So I’ve started putting attributions at the end of posts, and I apologize to folks whose images I’ve used in the mistaken belief I’ve been attributing them. I’ll be doing so for many of those old images as I use them again.
