Michael - first of all - good luck in your new home!
You, personally, cannot remove the photos.
I checked on the listing, and it says it was "claimed by the owner".
In that case, I believe you will need to have the former owner remove the listing, as I do not think the agent has control at this point.
It does show that the home is off the market.
You can email : Emily@Trulia.com for further help.
Good luck, and enjoy your new home!
