Hi John! Carol at Trulia here. We do have listings on Trulia that have drawings instead of photos but that is typically limited to homes for which construction is not completed and for which no photos were submitted. Any listing for which photos are received from the listing agent does display photos. If you are looking only at "New Construction" listings, there may not be photos available.
If you have further questions, please feel free to call Customer Service at 1-888-466-3501.
