Free Pictures for Writers
When preparing you book for publication you may find many uses for pictures either for illustrations or for your book cover. You need to be careful to use only public domain pictures or to pay for the photos. Royalty Free pictures must be purchased. Creative Commons or CCO pictures require you to mention the source of the picture (attribution). Even when you are checking sites that have public domain pictures they often show pictures that require purchasing. If a photo shows a watermark it is not free to use. Check the site for their policies. Different pictures may have different requirements.
