Comment (by Coatman):

 Using the GDAL Jasper-based JPEG2000, and without using Kakadu, I used
 GDAL 1.6 gdal_translate to create from a GeoTIF a GeoJP2, and then to
 create from that GeoJP2 a GeoTIF.  QGIS version 1.0.0-Kore-preview2, for
 Mac OS X 10.5, available from the Quantum GIS Downloads web site, and from
 the kyngchaos web site, both display the GeoTIF created by gdal_translate
 properly geo-referenced, with the proper number of columns and rows, but
 with the colors being ALL BLACK.  Additionally, all of the other image
 viewing applications that I have display the GeoTIF created by
 gdal_translate as all black.

 To summarize, I am reporting that a _GeoTIF_, created by gdal_translate
 from a GeoJP2 that gdal_translate created, is being displayed as all
 black, by QGIS and by 5 other image viewing applications.

 The sample GeoTIF, 800 columns by 100 rows, that gdal_translate converts
 to GeoJP2, can be downloaded from
