Images: Google Base--all that's fit to post

By clicking on a search item, a person will find out more about the posting, including descriptions, photos and contact information.
This person has a pricey apartment for rent. The listing includes a photo gallery to show off the unit.
Google provides a tool to let people input the information they want to share. It even includes a map--a Google map, of course.
People who list items can track them on a personalized management page.
