Not too sure what you mean by a purchasing agreement not being legal without it Ingmar?
I meant that distributing other people’s copyrighted work is generally not permissible (exceptions not withstanding), and you don’t need an additional “purchasing agreement” to make that clear. It’s simply the law.
What I am saying is that anyone who pays for an image signs to say that they will only use that image for the purpose they have paid for.
That’s my point, this goes without saying. But copyright law is a complex issue, and this forum is perhaps not the venue to really get into it 😊
If they then go and give that image to someone else they have broken the contractual agreement and this can then be used against them.
Why go to the trouble of using a contract (with the additional onus of proof that it was duly agreed upon, due consideration, ect ect) when the law will do just as well?
That is definitely perfectly legal, well at least where I come from anyway.
Probably, but almost certainly not necessary. Which was my point.
