Question:
How do you properly name cisco IOS images?

Followup:
I have been able to find the general syntax and such, but I have been unable to find any kind of list that explains the conventions to use for what different features of the router are. In searching for the answer to my question I have asked my CCNA instructor, Cisco Dealers, and I also spent several hours on the phone with Cisco Directly. Not to mention extensively searched their web site, and google searches.

I would be most grateful for any insights anyone has into another good place to look, something I may have overlooked, or the answer itself.
