Displaying Blog Avatar

I have a wpmu (still running 2.9.2) at onlineaor.com. I want to be able to display the blog avatar either in a widget or I can put it on the default theme. I am using the Blog Template plug in which works awesome! and I now want for each new Blog site created to display the blog avatar when it is created. I tried the author avatar widget plugin but that wants to pull the user avatar for authors and since this is a new site, the user will not have authored anything yet.
Help please
