Perfect, can we see the email in which your client/friend sends you these pictures and the authorization by the author for you to monetize these images please. Also please provide a way for us to contact the author of the images, since you give no credit or attribution whatsoever in the post.
I have an oral agreements with friends. Photos are not always sent to me by mail. I, unfortunately, do not save letters after use. I delete spam and unwanted letters.
I realized that now I have to save the letters for the report necessarily if the photos are from third parties. Otherwise, I am responsible for plagiarism. Did I understand correctly?
Sorry if I made mistakes. I do not understand the legal nuances.
