I wanted to take a photo from https://www.istockphoto.com/ and use it as a base to create a 3d model.
The photo would be an essential feature of the model, without the photo the model could not exist.
Would redistributing the model for free be possible following the license provided by the website? I would be happy to consider both the standard and extended license if any of those would allow me to execute and redistribute my work giving due credits to the author.
