Nandroid backups files (.img) created via Recovery are yaffs file system images. A tool called Unyaffs can be used to extract the files within these images (data.img / cache.img / system.img).
linux users can d/l the source code from: http://code.google.com/p/unyaffs/downloads/list
and compile using:
gcc -o unyaffs unyaffs.c
you can download the attached rar file and extract it...
1) copy the compiled unyaffs file/exe (along with cygwin1.dll) to a new directory
2) copy the nandroid backup image (data.img / cache.img / system.img) into that directory
3) go to terminal/command prompt, change directory to where those files are and execute:
e.g. for system.img
there is also an app in the market YaffsExpert with which you can extract the .img files using phone
