I am from Ukraine, photographer is from USA. We worked via upwork. We didn't have a contract, we just have the chat where first he allowed the usage and after being mad - no. There are jobs, which are like contracts but it is never specified about photo usage.
The old images that were already published in my portfolio I wasn't going to delete, because he has already given the permission. I wanted to know about the jobs that are still not published.
Thanks a lot.
