We are happy to discuss all issues, please contact our office to discuss. At a very basic level, however, we can offer that if you did not take a photograph or create a piece of art yourself there is a chance that it may be subject to the rights of another. Using your own work is always a good practice. If you want to use works of another, paying for licenses from reputable sources is always a good place to begin, giving not only the potential for an inference that you are acting in good-faith with respect to your attempt to properly license material for its use (should that license turn out to be unauthorized) but also an extra layer of security as you should be able to look to the licensor for indemnification should there be anything defective with the right to use the work.
