It's generally recommended to use Windows tools to do NTFS re-sizing.
I can't help with that, but from Linux you would need to run
kpartx -a -v /path/to/image/file
to create the /dev/mapper/loop?p? devices for the partitions within
the image. You can then access those devices just like regular disk
partitions.
Run "kpartx -d -v /path/to/image/file" to delete the loop devices.
