Whether at a small weekly or a major metro daily, if you are licensing photography from others or assigning others to make pictures, you have certain responsibilities.
If you don't already have them, you should develop company policies for licensing and contractor agreements and make sure everyone understands them. Your company can be liable for thousands of dollars if someone working for you misuses a photo - or abuses someone who produces photographs.
And by the way, you do not buy photographs; you license rights to use them. This is a key legal distinction that will lead you away from some serious mistakes.
