將評論直接添加為照片文件格式，而無需觸摸視覺數據
Digital photos (e.g. taken by your camera) are stored in your mobile as JPEG files. Thanks to the JFIF (JPEG File Interchange Format), digital photo data can be stored into file. But JFIF offers not only storing photo's visual data, but also offers storing other useful data (like user comments, Exif, ...). This application brings to you handy interface to attach (write, rewrite or remove) photo comments into JPEG file. If you copy your photo somewhere, comment is always travelling with photo and cannot be lost. Sure, photo's pixel data are not touched with text comments ;-)
