Depends on the theme really. Some, like Twenty Ten, have a built in way for each site to change the header image at will. You could look into that functionality, btu you’d need to code it into the theme.
If you go here:
http://wordpress.org/extend/themes/tag-filter/
and click the “custom header” option you’ll find 198 themes that match.

I don’t mind having to code this functionality into the theme. I just need to know where to get started. I have basic beginning PHP/MySql skills.

I was really asking how to code this functionality into my own themes… sry I was pretty unclear on this point.
Okay, I’m moving this to themes and templates, since at it’s heart it’s surprisingly NOT a multisite question but a ‘How do I code my theme to allow for customized headers’
I would start by unraveling Twenty Ten, but I’m not a themer 🙂
Haha… That’s where I originally posted and I got moved here.
O.k, so I found this page in the codex:
http://codex.wordpress.org/Function_Reference/add_custom_image_header
I’m at the point where I need to add function header_style() and function admin_header_style() to the site header and the admin header respectively. I’m not sure which files the terms “site header” and “admin header” are referring to. Can someone point me in the right direction?
uhhh… nevermind. Both of those functions need to be placed in functions.php. I got confused :/
So the add_custom_image_header function was what I was looking for. And I did it without any help… yay me!
