Add Lipstic to the list of new and useful online tools that combine photos or maps (or both) with listings.
Lipstic allows you to browse the offerings on Craigslist by only looking at the photos illustrating them.
To test it I started with their home page, then picked New Jersey, narrowed it to North Jersey, and picked Apts/ Housing for rent as the Category.
Above each photo, you can see the price. location and number of bedroom.
Click on one of the photos and a pop-up window gives you a more detailed listing.
All in all, fast, simple and practical. The only reservation I would make is that what appears to be different listings in the same town could be different pictures of the same place or item.

I discovered Lipstic on Monkey Bites.
