I use your plugin with the built in support of my theme (Weaver by Bruce Wampler) and I love it. Two blogs (one English one German site) having the same images in the header that's ok as both blogs simply differ by language.
Now I have a third blog in my WP multisite environment that also is willing to have random headers with own photos. And now I'm in trouble or not?
Is there a way to get different images be displayed per blog?
