Hello. Thanks for contacting me.

The real question is what the rights agreement says. If the copyright was assigned (essentially transferred) to the nonprofit org., then they own the copyright.

But if the agreement was a license to use the resulting work, then the copyright remains with the photographer (unless its been assigned to someone else), and he or she can sell the images elsewhere. However, its important to be sure that if the image was licensed, there is not an "exclusive" license for certain purposes.

For instance, someone might grant an exclusive license for use in a nonprofit's annual report. That would mean no other group can use it in an annual report. But other uses would not violate the license.

I wish you all the best in your work!

Hello again.

That really depends on how the agreement is worded. Because we are not equipped to review individual personal documents, I can only give information based on what you describe.

Think of the agreement as a contract. If you donated the image for use in a particular publication, then, as with any contract, as long as there is no breach of the agreement, it stands -- but can only be used for that specific publication.

If the agreement allows its use without stating restrictions as to publication, context, etc, then the terms of the contract will remain in force (unless there has been some breach of contract)

It may be that the organization is willing to remove the image. And often, in this type of situation, it may be possible to arrange something like that -- after all, a charity could be expected to show some gratitude.

In sum, only the agreement itself can say whether the photographer can revoke the license and under what conditions. If it is silent, without some breach of contract by the org to which the work was donated, the agreement stands. So read the doc carefully for any outs -- and then, perhaps, approach the org in a friendly way to see if they might be willing to do without it.
