In answer to your first question, not necessarily. A listing may have been on the market for a while, and the pictures were taken when the property was listed. In the meantime, the home could have been vacated. The opposite can also be true. I once had an agent from another company tell me she didn't bother to call to get showing instructions because the photos on the listing showed a vacant home. In the interim, the owner had put a renter in the property and she had a "24-hour notice to show" clause in her lease.
Many local Multiple Listing Services have a rule that forbids agents from using the photos from another agent who had the home listed previously. However, there is no guarantee that the MLS photos are current. Best way to know is to see for yourself.
