a tiny library 1k that only bothers with exif orientation
yeah there where a bunch of other exif libraries, but they are all complicated and we don't actually care about exif, we just want images to be the right way up!
var getOrientation = require('exif-orientation-lite')
var i = getOrientation(require('fs').readFileSync(image_jpg))
//machine readable orientation descriptions
console.log(require('exif-orientation-lite/machine')[i])
//human readable orientation descriptions
console.log(require('exif-orientation-lite/human')[i])
for testing you can also install -g exif-orientation-lite
and then do exif-orientation-lite images*.jpg
a list of files and their orientations will be output.
