Table of Anything! (Customized)

[Marcelo Reis]

Any one know how or where can I find information about creating a 
customized listing of anything?!

I mean, List of Pictures is ok (Standard) as well as List of Contents.
But what if I'd like to create a List of Pictures of My DOG and a List 
of pictures of my Cat and another List of picture of my Shark!?!?

Is there any special name for what I'm trying to do?!

Regards, and Thank you !
As usually you guys are helping me a lot finishing my thesis.
