Welcome to Trulia and thank you for your question. Only listings that have been submitted to Trulia manually can be edited at this time. Most of your listings come to us directly from Keller Williams and those without photos on Trulia also don't have photos shown on the Keller Williams website. Please contact Keller Williams to ensure that they add these listing photos to their website and also to the data feed they send to us. Once they provide the necessary photos to us, our site should update automatically to display the new images.
I hope this is helpful. Please let us know if you have any further suggestions or feedback.
