WordPress MU

   I'm running 61 blogs with MU, and I'm trying to be able to call the ID of a specific blog to serve up different header images. I'm limited in my PHP knowledge, and I've tried using the codex to no avail. For example (and I know this doesn't actually work, because the_blog_ID doesn't exist) -- I would put this at the top of my index.php file:

   <div class="blog<?php the_blog_ID(); ?>">
           This is the header.
   </div>

   So, if I'm on blog with ID 16, I have a class in my stylesheet with this:

   .blog16 {
         background-image: url(http://...);
   }

   And when a user is viewing blog 16, the unique image is displayed. If the user is viewing blog 24, a different image is displayed. I would have 61 different styles in the stylesheet, each with a different image.

   Any help getting something to spit back the unique blog ID, depending on the blog a user is visiting, would be greatly appreciated!

   Have you thought of adding the custom header option to the theme itself, and uploading the right header to each blog?

   Thanks for the reply, andrea_r!

   I found instructions for enabling the custom header in theme options (on another Web site, I think written by you?). They were very easy to follow, and it all worked!

   One question: Right now, the custom image appears at the very top of the header, underneath a banner advertisement at the very top. How do I control where the image appears in header.php? Using div tags in header.php? And if so, how would I do that?

   Yeah, I wrote that too. :)

   You'll have to read through the header.php of the theme, as well as the style.css.
