[FWTools] Large image creation for MapServer

[Bryan Keith]

Hello,

I have 3 band jpg (RGB) with 34925 x 36748 pixels.  I'm trying to create 
an image that will display quickly in MapServer.  After some testing it 
seems that both tiling and adding overviews to the image help a lot.  I 
can do a test with a smaller jpg and create an Imagine file that seems 
all right:

gdal_translate -of HFA -co TILED=YES --config GDAL_CACHEMAX 100 
Aerial_overall_fourmeter.jpg Aerial_overall_quartermeter_tiled.img

gdaladdo -r nearest Aerial_overall_fourmeter_tiled.img 2 4 8 16 32 64

However, when I run these same two commands on the large jpg, I get this 
error (repeated many times with slight changes):

Invalid argument
ERROR 3: Seek to 0:e3e6815e on 0xad2bf98 failed
Invalid argument
ERROR 3: Seek to 0:e3e6b15e on 0xad2bf98 failed

Using gdalinfo the new file looks OK except that the georeferencing 
information is gone:

Origin = (0.000000,0.000000)
Pixel Size = (1.00000000,1.00000000)
Corner Coordinates:
Upper Left  (   0.0000000,   0.0000000)
Lower Left  (       0.000,   36748.000)
Upper Right (   34925.000,       0.000)
Lower Right (   34925.000,   36748.000)
Center      (   17462.500,   18374.000)

When I view the image in MapServer, only the top ~2/3 of image draws. 
On disk I see that a couple files were created (one with 2 ** 31 - 1 bytes):

-rwxr-xr-x  1 bryan bryan 1294480699 May 31 18:46 
Aerial_overall_quartermeter_tiled.img
-rwxr-xr-x  1 bryan bryan 2147483647 May 31 17:47 
Aerial_overall_quartermeter_tiled.ige

What's the best way to accomplish what I'm trying to do?  Thank you,

Bryan
