In most cases you can't manually update your listing photo unless you've manually submitted the original listing information and photo to us via Trulia's Single Listing Submit. If you haven't done so then you should access your listing and click on the link to view additional property photos and details to find the source of the listing information we display. If you then update the photo on that website it should be updated within our display fairly soon thereafter.
If that doesn't work please access the link below to send an email to our customer service team with your listing information so they can investigate the issue.
