it's not life that matters but the journey...

Can someone help me? It's about Facebook - I want to delete some pictures that someone posted on my facebook, but I have no idea how to do it and can't find any tutorials. Is there any way to delete pictures once they've been posted? And also, how do I add pictures and make photoalbums on facebook? Seriously, either Facebook is the least user-friendly site I've ever seen (except maybe MySpace), or I'm really unbelievably stupid.

Thanks!!
