A while back I wrote a greasemonkey script for craigslist that allowed you to filter out any for-sale listings that didn't have pictures. It was called, NoPicsNoService, and after I was done I emailed Craig the link. He emailed me back that day and said it was cool. Less than a year later, that feature was built into craigslist.
