Did you claim ownership of the property in Trulia? From clicking the link to the property you provided that looks like the case. If so, I don't think the listing agent will be able to make any changes and you'll probably have to work with Trulia directly to request that the photos be removed.

Once the information has been syndicated to Trulia through the MLS they can do what they want with it without recourse. Even after it is sold and closed it could remain on the web, not much you can do about it after the fact. For next time indicate to your agent to not let it go to the internet.
If the property has closed you could contact the listing agent right now. I have done this for buyers that had the same concerns after they have moved into my listings. It is still listed as pending.
