I'm wondering if it is at all possible to buy the trademark of an image? I have a customer that would like an image from Adobe Stock to be the face of his company but he's worried that too many people will end up with the same image.
It is not possible to buy the trademark of an image, however, you may go ahead and modify the non-editorial asset in any way you deem necessary.
Note: Your modifications must not violate or infringe on the intellectual property or other rights of any person or entity, nor place the author or the model in a bad light or depict them in any way that might be deemed offensive. For more details you may refer to Common Questions, Adobe Stock
Additionally, I would like to let you know that if you are using the unmodified images, you need to provide credits to the photographer, however, as per the licensing terms if the image is modified then the attribution is not necessary however, you can still give the author credits on a separate credit page which is an optional choice.
Hope this information helps!
Feel free to update this thread in case of any additional questions.
Very helpful, thank you.
One more question:
If I were to add text to the image and then print it on some t-shirts, would I need to credit the artist in some way? I would be purchasing the extended license, of course.
In order to add text to the image and print it on t-shirts, you would require an Extended license, however, it is not important to add credit to the artist in this scenario.
