A scientific paper to be published contains an image of someone famous. An image is just picked from the Internet.
Is it a violation to publish such image without permission?
From whom a researcher needs to seek the right to this image: the famous individual or photographer?
Suppose the image is eventually published in the paper without permission while the journal did not ask for permissions. When the paper is published the author grants the journal rights to publish this work. To best of my understanding, legally the author is not the owner of his paper anymore. The paper is published under Creative Commons license. In such a case, who is legally responsible for the violation: the author or the journal? Who can be potentially sued?
1) How can I know which image I can use without a permission? For example, an image in Wikipedia can be used? I know that I can buy from stock images, but there is only limited number of images there.
2) For obtaining the permission, how I can know from whom to ask? For example, an image appear in some news article. But they could also obtain a permission to it.
