JPG files can contain EXIF data, which specifies it's orientation. This is good, because JPEG is lossy format and every time you reencode it, you loose some information. Doing real rotate in file is not possible without reencoding. The problem is, not all software can handle EXIF rotate right. But GIMP can, it asks on opening, whether to rotate the image or not (since it has to reencode it anyway).
