I just found this site http://dannydouglass.com/post/2008/02/New-BlogEngine-Extension-SlideShow-Photo-Gallery.aspx that has a great implementation of a SilverLight photo gallery with BE.N. I am going to start using it for awhile until I can create an XML version for BE.N. I highly recommend it. It is easy to use and set up. The only downside is that it is not each author only for a site.
