I would like to publish an ebook book with Adobe Stock photos in the editorial area. Do I have to provide the copyright information directly on the page with the photo? Or can this information also be at the end of the book in the imprint, with mention of the corresponding book page?
In the licensing terms, Adobe says, "at an appropriate place" (bold is mine).
(B) you must include the accompanying credit line or attribution, placed in a way that is reasonable to the applicable use, in this format: “[Contributor Name]/stock.adobe.com”, or as designated on the Website;
With books, the credits are very commonly grouped at a specific place.
Look here for more information on licensing: https://community.adobe.com/t5/stock/links-for-licensing-terms/td-p/11366788
(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
OK, thanks 😉
