I am not clear on your question. Do you mean removing photos of a home you just purchased from the MLS? If so, that will probably not happen. The photos will stay on the MLS as a sold listing. Years from now, when you decide to sell, agents can still pull the photos from the previous listings.
If you are referring to your property listing still showing active on third party sites even though it's already sold, they will eventually be removed or marked as sold but sometimes it takes weeks for that to happen.
