I am thinking about publishing a text with pictures where the text and most of the pictures are my own, while some of the pictures are by others. Those others have agreed with the inclusion of their pictures. Ideally, I would like to publish the result under a licence of the CC family.
It is my understanding that to do this, I would need the copyright holders of the different pictures to release there work under the specific CC license. Which I will never obtain.
My alternative plan was to include a copyright statement in the style
All text and the pictures where no photographer is indicated are my own work and available under the CC-whatever license. For other pictures all rights belong to the photographer and his permission is required for any use.
Is this a viable approach or does this approach have dangers that I am ignoring? Is there maybe a better approach to make the result as open as possible? And am I correct that in this scenario the resulting work would be closed and not available under any specific license?
