Welcome to Trulia Voices and thank you for your question. There are several options that you can take advantage of in order to add your virtual tours to your listings:
1. You can contact the source that provides us with your listing information (Prudential in your case) and request that they add your virtual tour information to the data feed they send to us.
2. You can ask your virtual tour provider to send us a data feed of their own.
3. You can submit your listing information to us via our Single Listing Submit platform and be sure to include your virtual tour link. Access http://www.trulia.com/submit_listings/ if you'd like to do so.
No matter which option you choose, once we receive your virtual tour information, our display should update automatically to include that new information in our display of your listing.
Please let us know if you have any additional questions or feedback for us.
