It's a great idea to add photos or videos - research shows that they drive more traveler engagement with your listing page. Add photos or videos to your listing through the Management Center. If you haven't yet registered for the Management Center, visit www.tripadvisor.com/Owners to get started.
Once you're logged in, select your business at the top right-hand corner of your screen. Click the “Profile” tab, then select “Add new photos and follow the instructions to upload your materials. You can also return to this page to manage your photos or videos later. Want more detailed instructions?
