		Beyond "progressive" there are now two rather different version of JPEG, the JFIF format and the EXIF one. JFIF is the "traditional" one, EXIF is a bit more recent and more complete (can also include sound...). AFAIK Gimp produces the JFIF, bt this could be a matter of library used.
The format is reporded by ImageMagick's identify -verbose.
