You can add the photos yourself by claiming the listing here on the Trulia site as the agent. To do this, first bring up the address of your listing, then there is a small tab that says "claim this home". The site will have you verify that you indeed are the agent. Once completed then you can click on the "edit" tab to add photos, add copy, a virtual tour, and Open House dates and times. The listing will then appear under "My listings" tab under your name in the upper right hand corner for you to edit anytime.
Hope this helps.
