MetaIO Image from ITK also writes out the ITK's Meta Data Dictionary along with the image. The dictionary can contain arbitrary information. These fields looks like they came from a NIFT file:<br>

It is generally more productive to learn how to use existing libraries as opposed to hacking your own for IO. This help ensure that everyones files are compatible and usable.<br>
