You were paid by this employer to do this work. You designed a website and graphics that were used by their business to promote their business. That is your contract, you were their employee. Any work whether it be design, arts, or working on cars- while employed by that business is owned by them- if it was done for that job. If you design a graphic on your own computer at home, never show it to them- and then after leaving you decide to use the same design somewhere else that is fine. It is not okay to use one of the designs you made for the former employer again. But honestly this is not something you should ask an internet forum about, you should seek legal advice from a legal professional.
