JavaScript Load Image Demo

JavaScript Load Image is a library to load images provided as File or Blob objects or via URL.
It returns an optionally scaled and/or cropped HTML img or canvas element.
-It also provides a method to parse image meta data to extract Exif tags and thumbnails and to restore the complete image header after resizing.
