Currently I'm writing a book, in which it would be interesting to include some relevant pictures. The pictures I'm planning to include are in the public domain. Here is an example.
That picture, according to Wikipedia, is in the public domain. So I would like to simply download it, include it on a page of my book, and sell that book. Note that the picture serves a purpose of illustration within the book, which is actually original content written by me.
Can I do this:
- By simply adding a "Disclaimer/Copyright notice" at the beginning of the book, stating something like "all pictures in this book are in the public domain, no copyright infringement is intended, blablabla"?
- Not attributing the image to any person that was involved in taking the picture, or uploading it to Wikipedia?
- Do the same with about 20 more images that are relevant to my book, each time not specifically mentioning the copyright info or in which country it is public domain, just the fact that "all images are public domain"?
