Note that this uses the "Lossless" approach - in order to preserve data embedded in the EXIF segment that it can't parse (such as Maker Notes), this algorithm avoids overwriting any part of the original segment that it couldn't parse. This can cause the EXIF segment to grow with each update, which is a serious issue, since all EXIF data must fit in a single APP1 segment of the Jpeg image.
