I don't know much about craiglist, and I don't know what "ghosted" means. I would make a formal sounding letter, and send it to the person, who stole you pictures, but I don't really know the rules on the web for pictures, do you know how to watermark them? That might give you more power in the future. Sorry, people are so unreasonable over the holidays, you need so much patience to deal with last minute Christmas Shoppers. Happy Holidays!
