Sort and/or Group host by IMAGE ID

[knightsaint]

I would like to be able to search and/or sort my host by Image ID. I was informed that on .32 there are some php files to modify but I just want to know exactly what to modify before I go breaking my system. Here are the files mentioned.

you need to edit:
/var/www/fog/management

include folder:

1. hosts.list.include.php
2. hosts.search.include.php

and in ajax folder:

1. host.search.php

Any more clue on what exactly I need to change or is it just as easy as adding a line for image id right before the mac address line? If so what is the correct syntax?

Thanks for any and all help.
