You're searching for images to use in a book you're working on. You find an image with a Creative Commons license on Wikipedia or some other website. So you use it, adding the proper attribution.
But after your book is published, you're sued by someone for copyright infringement. Turns out user "nox7" uploaded a copyrighted image, falsely claiming it was licensed by CC.
If the website you got the image from is still online - solid evidence that you were duped - what bearing, if any, might that have on your case?
I'm assuming you can still be sued, and you could lose. But are there cases where a court says, "Hey, this guy was lied to. He made an honest effort to ascertain the image's legal status, but he was duped by user nox7"?
The judge then throws the case out, on condition that the image be removed from future copies of the book. Or the defendant still loses, but he gets off with a light fine.
Can anyone give me some guidance here? If there's no definite answer, it would be helpful to know about specific cases involving this situation.
