How do I get to Step 2 in the instructions? I don't see that screen anywhere in iTunes 11.0.1.12.

I'm trying to get set up to show photos from my PC on the Apple TV. I've got AppleTV configured to the PC's iTunes library. The instructions say I need to go to the Advanced menu. The only one I can find is under Preferences, and it doesn't look a thing like the instructions listed on this site. The iTunes library has Music, Movies, TV Shows, Books, etc., but it has no Photos section. I just want to show photos that I already have on my home PC on my Apple TV. How do I do this?
