The site is only as good as the agents that provide content. You can always "claim" your home and upload the correct photo of your home on the Trulia website. Or you can have your Realtor do this for you if your selling your home.
The site has been around for a few years and it is getting better. However if you seriously want to market your home hiring a Realtor to help you will be the most beneficial move. A Realtor can add your home listing to multiple sites and most importantly add it to the MLS-Multiple Listing Service. This will allow even more potential buyers to see your home.
I wish you the best and please let me know if I may be of further assistance.
