If a website uses pictures on some pages that are under cc-by-sa. The images have been modified slightly to fit into the page. What is the derivative work?
- only the images themselves
- only the part of the page that uses the image (i.e article copy, but not navigation, logo, etc.)
- the whole page
- the whole website
Or maybe there is no derived work at all and it is a collection? Can anyone shed some light on this?
