I combined the random photo block with Beckett's featured photo block.
For the random part I changed the link for the picture to reflect the album link not the picture link as I was getting to many $id=unknown errors.
Also add a little piece of code to give the total count of photos in the Gallery.
If you can make it better please do.
Change http://www.youraddress.com/ to the URL pointing to your Gallery and install the random block and featured block as per their instructions
