Welcome to Trulia!
I apologize for not finding and answering your question much sooner. In the future when you have a question about Trulia, please post it in our Using Trulia category so we can find it right away.
The three listings shown on your profile come to us from your MLS via ListHub.net. If you updated these photos with your MLS, they should be up-to-date at this point. If that isn't the case however, please contact our Customer Service Team so they can investigate. To do so just access the link below and select the 'Ask a Question' option and be sure to provide a link to the listing in question.
Have you tried going into your listings under the quick links. You can also find the "My Listings" option if you hover over the My Trulia drop down menu at the top right of the page. This should pull up all of your listings. You will see below the picture of the home where it says update details. Click on that and then hit the continue button on the bottom of that page, The next page is the photo page where you can delete and add photos.
Hope that helps!
