last posts slideshow in header

Hello, I am a little noob with wordpress and i would like to know how to include in the header of my web a slideshow showing last posts that have been written, their title and their image.

My web is http://www.guitareview.es; as you can see, is prepared to include the slideshow but I am not capable to do it. I’ve tried smooth gallery but I don’t know how to do it. thanks and sorry about my english.
