Find the hash of the file you desire. You can perhaps find this in the 'Notes' or 'Comments' section which is open to public, and removing the 'preview' part from the path of said preview image. E.g. http://s3.amazonaws.com/danbooru/preview/2503b71d67bc18b7712562053b2eb2ab.jpg becomes http://s3.amazonaws.com/danbooru/2503b71d67bc18b7712562053b2eb2ab.jpg

Big hassle for something you can't easily search, and trivially patched but the more you know!
