Twenty Eleven: Multiple rotating headers

Hello everyone,

I have been using the twenty eleven rotating header for the sub pages of my school website. Example:

http://www.inrf.uci.edu/about/

I am in the process of redesigning the homepage and want to incorporate a second rotating header that is a different size and with separate images.

The php code for the banner is in functions.php, but I can’t figure out what part of the header code I need to duplicate and change. I’m more of a designer than a programmer, so I have only a familiarity with php.

I would appreciate any help.

Thanks
