The explanation to picture #2 is simply one of the coolest things you do while you're in Ireland. If you don't do this while you're in Ireland, you haven't "done it all". What that guy is doing is kissing the "Blarney Stone". This stone is constructed in the Blarney Castle in Cork, Ireland, and to kiss it, you have to lay on your back, use the iron rods to stablize and hoist yourself up, then you kiss the stone while you're upside down. It's an old Irish fable that it brings you luck and love (a lot of people say that you will get "lucky" the day that you kiss the stone, too). To read a little bit more about it, go here.
