It's a great idea to add photos - research shows that they drive more traveler engagement with your listing page. Add photos to your listing through the Management Center. If you haven't yet registered for the Management Center, visit Tripadvisor.com/Owners to get started.
Once you're logged in, look for your business at the top right-hand corner of your screen and select it from the dropdown menu. Hover over the “Profile” tab and select “Manage photos" to upload your materials. You can also return to this page to manage your photos later.
