Lots of sites now feature tutorials and e-books that use Creative Commons (CC) pictures (from Flickr, for example) to illustrate an article. It’s quite “deceiving” because the pictures are not taken by the author. Printed magazines do that all the time. But can you use a CC picture where there is a distintly recognizable face on the cover of your {free) e-book?
Carolyn Wright answers that question in Black Star Rising.
