Welcome to Trulia Voices and thank you for your question. Listings are generally sent to us via feeds from other sites, however your listing agent can also upload photos to the listing directly on our site.
I recommend that you contact your agent. He or she can then follow up with the source of this listing information to make sure they are sending all the listing photos to us, or manually upload the photos.
I hope this helps you. Please let us know if you have any other questions or feedback for us.
