Can I use a licensed image as a trademark?
The related conversations answered the question....No
No. A clear no.
The problem is that you get a nonexlusive license to use that asset. So other people can use the same asset. This means that you can't register the asset for exclusive use, which a registred trademark is.
You'd need to own the photo, not just have a nonexclusive license. That would mean an exclusive license with a photographer. (Note that if a photographer just takes a photo for you without a "work for hire" contract, the photographer still owns it).
