I run BitPixels (http://www.bitpixels.com http://www.bitpixels.com) that provides automated website thumbnails. I actually purchased Bitpixels from another HN member a few years ago and have continued to build and market it. The primary marketing channel is offering a free account that requires attribution on their site (e.g. "Thumbnails powered by BitPixels). The attribution links drive several new users per day and some eventually convert to premium accounts.
