The 'tile index' layer was created via an ArcGIS extension written by
Mike Juvrud of Mud Labs. What it does is takes the Orthophoto/raster
image from a MrSID format, and chops it up into tiles, outputting the
tiles as TIFF formatted images (max 50MB per image). At the same time,
it generates the 'tile index' layer, filling in the corresponding
filename in an attribute named 'PATH'.
After verifying this method worked using TIFF files, the 'PATH'
attribute was changed from a .tif extension to a .jp2 extension. So if I
had an image named '104.tif' the new name would be '104.jp2'
I used the 'jasper' utility to convert the TIFF image to a JPEG2000
using the command: 'jasper -f 104.tif -t tif -F 104.jp2 -T jp2'
Here is the output from ogrinfo of a TIFF version, and another of the
JPEG2000 version.

I hope I covered all the bases. If you need any more info, sling your
questions my way.
