I will take a look.

JPEG driver is based on IJG libjpeg library. It is implementation of the
`old' JFIF compression standard. JPEG2000 introduces completely new
compression scheme and file layout. GDAL has two JPEG2000 drivers:
`JPEG2000' based on free JasPer library and `JP2KAK' based on non-free
JPEG and JPEG2000 are different drivers and you don't need JPEG2000 if
you only need to handle JFIF files.
