Minor but...
"JPEG lossless rotation will modify original file(s), and remove some unused pixels (width and height must be multiple of 8 pixels)!..."
is not correct, it should be
"JPEG lossless rotation will modify original file(s), and may remove some unused pixels (width and height must be multiple of 8 pixels)!..."
or
"JPEG lossless rotation will modify original file(s), and some unused pixels may be removed (width and height must be multiple of 8 pixels)!..."
Because in most cases no pixels are removed. Hope may is the right term, or might?
