I think he means doing something like this example:

http://michaelgalloy.com/2006/04/15/idlgrimage-tiling-in-idl -62.html

This example uses a JPEG2000 image as an example file, so the "pull
out the chunks you need" part is easy. But it is an example of how to
use tiles with IDLgrImage and IDLgrWindow.
